SUMMARY

This study was done to determine efficient method and appropriate time of harvesting seed from Andropogongayanus thereby delivering the information and knowledge to private and public forage seed producers.The study was conducted in research field of Assosa Agricultural Research Center for three consecutive years with treatment set up of factorial combinations of four harvesting methods and four harvesting times with four replications. The harvesting methods were hand plucking/mowing of ripened panicle, shaking the panicle at harvesting allowing the ripe seeds to fall in nylon net collecting bags attached to stems, sweeping of fallen seeds from the ground after previously cutting of the dry stems and mowing of panicle with half-mature seed and sweating it in a shade. Time of harvest schedule defined by number of days after peak anthesis; and the treatments were 14th, 21st, 28th and 35th days. Data were analyzed by SPSS computer software using GLM procedures. The overall mean seed yield and germinable seed yield (kg/ha) recorded in the study were 561.3 and 309.9, respectively. Highly significant (P<0.001) yield differences were recorded for germinable seed among harvesting methods and time of harvesting. The interaction of harvesting method and harvesting time was also significant (P<0.05).The most efficient method and appropriate time that maximum germinable seed yield attained was sweating on 28th day followed by mowing on 21st day; and the least germinable seed yield was attained by sweeping on 14th day. Thus, we recommend farmers and seed producers growing Andropogongayanus in Benishangul-Gumuz and in similar agro-ecologies to harvest seed by sweating on 28th day after peak anthesis..

SUMMARY

For improving the carbon storage in agricultural soil, cropping with best mangement practices is important. Among crops, forages have great oppourtunity to fix carbon. As well as the undisturbed cultivation for long period, poses to select these crops for carbon sequestration studies.The objective of this paper is to study the impact of various nutrient sources on biomass yield and carbon sequestration potential of various perennial fodder crops. An experiment was initiated with three different perennial forage crops viz., legume fodder (Lucerne CO 1), grass fodder [Cumbu Napier hybrid grass CO(CN)4] and cereal fodder [sorghum CO(FS)29]. The nutrient requirement met through different sources viz., farm yard manure (FYM), poultry manure (PM), INM and inorganics. The results showed, among the different forage crops, Cumbu Napier grass had higher carbon sequesteration potential of above ground biomass which removed 336.7 t CO2/ha than multicut fodder sorghum (148.7 t CO2/ha). The higher below ground biomass in Cumbu Napier grass removed 7.73 tCO2/ha from the atmosphere than lucerne (4.21 t CO2/ha). The soil physical properties and microbial populations were also favourable in the grass type fodder. Among the nutrient sources, the FYM favoured higher carbon fixation in the soil than poultry manure, integrated nutrient management and inorganics alone. In addition, the Cumbu napier fodder crop stored 9.2 g/kg of soil organic carbon over initial SOC status of 6.5 g/kg followed by multicut fodder sorghum accumulated (8.7 g/kg). The soil carbon stock was worked out to be 18.63 t/ha/year in Cumbu napier grass than by multicut fodder sorghum 17.62 t/ha.

SUMMARY

Rust caused by Puccinia substriata var. penicillariae is one of the major diseases affecting both food grain and forage production in pearl millet. In order to find out economical and cost effective method to manage the disease, attempts were made to identify resistance sources against rust by screening of germplasm. The field screening involved the use of a highly susceptible line as infector row grown after every three test rows under natural epiphytotic conditions. Observations on rust severity were recorded at grain filling stage. In all, 228 entries of coordinated trials, none of the entries was free from rust severity, 10 entries showed 0.1-20 per cent rust severity, 48 entries showed 20.1-40 per cent rust severity, 80 entries showed 40.1-60 per cent rust severity, 67 entries showed 60.1-80 per cent rust severity and 23 entries showed more than 90 per cent rust severity. Amongst 276 entries of state trials, 39 entries were free from rust severity, 188 entries showed 0.1-20 per cent rust severity, 71 entries showed 20.1-40 per cent rust severity, 15 entries showed 40.1-60 per cent rust severity, two entries showed 60.1-80 per cent rust severity and none of the entries showed more than 80 per cent rust severity.

SUMMARY

The experiment was conducted at G. B. Pant University of Agriculture & Technology, Pantnagar, U. S. Nagar, Uttarakhand, India during kharif seasons of 2013 and 2014 (sown on 10th June and 15th June) to test intercropping treatments for optimizing seed rate. The experiment was laid out in randomized block design consisting of nine treatments (sole sorghum, sole cowpea, sole ricebean, intercropping of cowpea and ricebean each with at 25, 50 and 75 per cent of recommended seed rates) with sweet sorghum. The recommended fertilizers viz., nitrogen (N) and P2O5 120 and 60 kg/ha for sole sorghum, 20 and 60 kg/ha for sole legumes and 80 and 60 kg/ha for intercropping systems, respectively, were applied. In sole sorghum 2/3 N along with all Phosphorus were applied as basal and the remaining 1/3 N top dressed at 30 DAS. In legume crops, whole nitrogen along with phosphorus was applied as basal. The findings revealed that intercropping of cowpea with 25% seed rate maintained higher green forage, dry fodder and digestible dry matter yield in sweet sorghum as well as the system productivity compared to remaining treatments, however, it was at par with sweet sorghum+cowpea (50%) intercropping treatment. Intercropping system reduced green forage, dry fodder, crude protein yield and crude protein content of cowpea and ricebean but enhanced the digestible dry matter yield. However, the digestible dry matter content of cowpea and ricebean remained unaffected.

SUMMARY

A total of 20 marvel grass genotypes were grown in randomized block design (RBD) with two replications at Grass Breeding Scheme, Mahatma Phule Krishi Vidyapeeth, Rahuri, District Ahmednagar, Maharashtra during kharif season of 2015-16. Objectives of investigation were to study genetic variability, correlation and path analysis for 13 characters viz., days to 50 per cent flowering, plant height (cm), number of tillers/tussock, stem thickness (mm), number of internodes/tiller, internode length (cm), number of leaves/tiller, leaf length (cm), leaf breadth (mm), green fodder yield (g/tussock), leaf : stem ratio, dry matter (%) and crude protein (%). Treatment differences were found to be significant for all the characters studied. Characters like number of tillers/tussock, stem thickness L : S ratio and green fodder yield showed high GCV and PCV. The estimates of genotypic as well as phenotypic coefficients of variances were the higher for leaf : stem ratio, stem thickness (mm), green forage yield and number of tillers per tussock. Maximum heritability (b.s.) was observed for leaf : stem ratio (97.10%) and minimum for dry matter (61.90%). High estimates of heritability accompanied by high estimates of genetic advance as percentage of mean were observed for characters like number of tillers/tussock, stem thickness, L : S ratio, number of leaves/tiller, leaf length, leaf breadth, crude protein (%) and green forage yield indicating that these traits are predominately governed by additive gene action and selection for these characters will be effective. The characters like days to 50 per cent flowering, plant height, stem thickness, number of internodes/tiller, number of leaves/tiller, leaf length and leaf breadth, showed significant positive genotypic correlations with green forage yield. Plant height and leaf breath exhibited high positive direct and indirect effect and significant positive genotypic correlation with green forage yield. The characters viz., number of internodes, stem thickness, leaf length and number of tillers/tussock also exhibited high indirect effects. Thus, emphasis should be given on these characters for green forage improvement in the present marvel grass.

SUMMARY

The experiment was conducted at the research farm of Department of Genetics & Plant Breeding, Chaudhary Charan Singh Haryana Agricultural University, Hisar from 2007 to 2010. The experiment consisted of eight treatments viz., two management levels i. e. Farmers practices [No application of DAP, sub-optimal use of N @ 25-30 kg/ha, no gap filling and thinning and hardly one interculture operation] and recommended package of practices under rainfed situation [Nitrogen @ 40 kg/ha and P2O5 @ 20 kg/ha, gap filling and thinning (three weeks after sowing) and one interculture operation] along with four cultivars i. e. two hybrids (RHB 121 and GHB 558) and two populations (Pusa 383 and Raj 171). The adoption of recommended practices enhanced the productivity by 23.5 and 18.5 per cent in hybrids and populations, respectively, as compared to farmer’s practices. Among hybrids and populations; the hybrid GHB 558 (30.58 q/ha) produced significantly higher grain yield than RHB 121 hybrid (27.10 q/ha), populations Raj 171 (26.91 q/ha) and Pusa 383 (26.64 q/ha). Sustainable yield index (SYI) was quite higher in recommended package & practices (0.61) than the farmer’s practices (0.33). The SYI was comparable in the population Raj 171 (0.66), hybrid GHB 558 (0.65) and RHB 121 (0.63) but quite superior to Pusa 383 (0.49) in the recommended package of practices. In farmer’s practices, the SYI was found maximum in hybrid GHB 558 (0.42) and it was followed by Raj 121 (0.37), RHB 121 (0.30) and Pusa 383 (0.22) cultivars. The study indicated better performance of both the hybrids GHB 558 and RHB 121 than the populations Raj 171 and Pusa 383 under both the management levels

SUMMARY

A study was made in Sorghum bicolor with line × tester (6 females × 4 males) to estimate the fodder yield and its component traits of different hybrids and parents under different environments. For this purpose, 24 specific cross combinations were developed by using 10 diverse parents during kharif season in 2014-15. These hybrids along with 10 parents and two standard checks (SSG 59-3 and MFSH 4) were evaluated at two locations (Hisar and Karnal) with early and late sowing during kharif season in 2015-16. The analysis of variance indicated the presence of variability among hybrids and their parents. Among male parents (HJ 541 and G 46), among female parents (467A and 56A) and crosses 467A × G 46 (222.1 g) and 465A × HJ 513 (220.8 g) showed higher green fodder yield on the basis of overall mean. This hybrid was also good for plant height (141.9 cm) and leaf length (81.7 cm). Other hybrids that showed better green fodder yield were 9A × IS 2389 (193.8 g), 56A × HJ 513 (190.0 g) and 31A × HJ 513 (185.9 g). Hybrid 56A × G 46 recorded higher leaf length (86.3 cm) and was also better for green fodder yield (178.3 g) and plant height (159.4 cm).

SUMMARY

Fifty genotypes of oat were evaluated to study the character association and path coefficient during rabi 2014-15. The correlation studies revealed positive and significant correlations of seed yield/plant with 100-seed weight, number of spikelets/panicle and number of tillers/plant. Strong association of these traits revealed that the selection based on these traits would ultimately improve seed yield and it was also suggested that hybridization of genotypes possessing combination of above characters was most useful for obtaining desirable high yielding genotypes. Path coefficient analysis revealed that 100-seed weight, number of spikelets/panicle, number of tillers/plant, plant height, flag leaf length, internode length, axis length and days to maturity had positive and direct effects on seed yield/plant, while the characters viz., days to 50 per cent flowering and peduncle length showed direct negative effects. The results revealed that the traits like 100-seed weight, number of spikelets/panicle and number of tillers/plant should be given due consideration while performing selection for seed yield in segregating generations of oat.

SUMMARY

A field experiment was conducted during kharif season of 2015 at Udaipur, Rajasthan on sandy clay loam soil to assess the effect of fertility levels on multicut genotypes of forage sorghum. Among multicut forage genotypes, CoFS-29 proved most efficient as it gave significantly higher green (74.78 t/ha), dry (23.77 t/ha) fodder yield on the basis of the total of two cuts, net monetary returns of Rs. 66430/ha and B : C ratio 2.15. The crop fertilized with 125 per cent RDF recorded significantly higher green and the dry fodder yield on the basis of the total of two cuts over application of 50, 75 and 100 per cent RDF. The magnitudes of the increases were 35.52, 19.82 and 8.82 per cent in total green fodder, and 45.13, 18.90 and 9.63 per cent in total dry fodder yield, respectively. Application of 125 per cent RDF also fetched highest net returns (Rs. 71814/ha) as well as the maximum B : C ratio (2.23) as compared to lower fertility levels.

SUMMARY

The experiment was conducted to evaluate the relationship among 17 quantitative traits. The 63 single cross hybrids developed from crossing nine productive maize inbred lines with seven quality protein maize inbred lines in line x tester mating design along with their parents and standard checks were evaluated through correlation studies at experimental area of CCS Haryana Agricultural University Regional Research Station, Uchani, Karnal during 2013-14. Correlation is important in estimating the relative importance of various characters on grain yield. From the association analysis, it was found that grain yield per plant showed significant positive correlation with days to 50 per cent tesselling, days to 50 per cent silking, days to maturity, plant height, ear height, cob length, cob diameter, number of grains per cob, 100-grain weight, shelling percentage and lysine content, whereas it was found significant negative with protein content and starch content. Among yield and quality characters, grain yield per plant had significant negative correlation with protein content and starch content. Protein content had significant negative correlation with tryptophan content and tryptophan was significantly positively correlated with lysine content. While oil content and lysine content exhibited positive and significant association with grain yield per plant but with tryptophan content, grain yield per plant showed positive but non-significant association. Strong positive and significant association was established between lysine content and tryptophan content. Hence, days to 50 per cent tesselling, days to 50 per cent silking, days to maturity, plant height, ear height, cob length, cob diameter, number of grains per cob, 100-grain weight, shelling percentage, oil content and lysine content, tryptophan content should be given more importance while formulating selection indices for grain yield improvement in maize.
