SUMMARY

Genotype x environment interactions and stability parameter analysis are of major importance to sort out high yielding and stable hybrids. Forty-five hybrids and 14 parents were evaluated during kharif 2012 (E₁), rabi 2012 (E₂) and summer 2013 (E₃) seasons to identify stability for green forage yield per plant in forage maize. G x E (linear) and G x E (non-linear) were found significant for fresh green stem weight per plant and green forage yield per plant. Among the parents, GWC-0401 had above average stability, thereby specifically adapted to poor environment. Among the hybrids, IC-107121 x GWC-0511 and African Tall x GWC-0401 had average stability, which indicated that these hybrids would be well adapted over range of environments, while the hybrids IC-130726 x GWC-0512, GM-6 x IC-130693, GM-6 x GWC-0512, J-1006 x GWC-0319, J-1006 x GWC-0511 and J-1006 x GWC-0512 had below average stability, thereby specifically adapted to favourable environment, whereas the hybrid IC-130726 x GWC-9603 had above average stability, thereby specifically adapted to poor environment.

SUMMARY

Six entries of forage maize (JHM-13-1, BAIF Maize-3, AFM-3, AFM-2, PFM-7 and AFM-1) were evaluated along with two national checks viz., African Tall and J-1006 for assessing their fodder yield potential and quality parameters in trials during kharif 2013. The same set of entries was also tested at 21 different locations distributed in the five zones for fodder trial. Highest green fodder yield (695.7 q/ha) was recorded at Hyderabad followed by Raipur (616.6 q/ha) and Coimbatore (523.1 q/ha), whereas highest dry matter yield (129.5 q/ha) was recorded at Raipur followed by Bhubaneswar (117.2 q/ha) and Ranchi (108.9 q/ha). Highest per day production of green fodder was recorded at Bhubaneswar and Hyderabad [GFY (q/ha/day)– 10.63 and 10.03, respectively] followed by Ranchi (9.55 q/ha/day). Highest crude protein was obtained at Raipur (12.7 q/ha) followed by Coimbatore (9.3 q/ha) and Bhubaneswar (9.2 q/ha). Data revealed that southern zone represented by Hyderabad and Coimbatore gave higher green fodder yield, plant height and production efficiency thereby indicating that climatic conditions and soil types were very suitable for production of fodder maize.

SUMMARY

Field research was conducted at Research Farm of CCS Haryana Agricultural University, Hisar to
evaluate the relationship of crop growth, fodder biomass and yield with agrometeorological indices in pear millet. Pearl millet crop was sown in randomized block design with 13 fertility levels of nitrogen (N), phosphorus (P₂O₅), and potassium (K₂O) and in three replications. Agrometeorological indices : thermal, helio-thermal and photo-thermal units were computed for all the fertility treatments using weather data recorded at agricultural meteorological observatory. Efficiency of thermal and radiation energy conversion into dry biomass was computed using the thermal and radiation indices. Agrometeorological indices and crop parameters were correlated for developing regression models to predict the different plant biometrics as dry matter, yield and leaf area index in pear millet crop. Yield and yield traits (grain yield, stover yield and biological yield) were correlated with photothermal unit (PTU), thermal (TUE) and radiation use efficiency (RUE) showed higher correlation coefficient with RUE as compared to TUE. The multiple regression models developed for prediction of leaf area index (LAI) and dry matter (DM) based on agrometeorological indices are as under :

DM=0.658-.000056×PTU+90.662×HUE-0.117×RUE                                                           (R²=0.98)
LAI=1.895+0.006×4HUE+0.726×RUE                                                                                    (R²=0.74)

Agrometeorological indices were explained up to 74 and 92 per cent variability in leaf area and dry
matter, respectively.

SUMMARY

The present investigation was carried out to observe the different morphological variations induced
by chemical mutagen ethyl methane sulphonate (EMS) on clusterbean commonly known as guar. Guar is an important forage crop with versatile properties. The importance of guar is mainly due to presence of guar gum produced from its seeds. EMS is a chemical potent mutagen, capable of inducing large number of mutations. Various morphological variations were produced due to treatment of EMS. Seed treated with 0.5 per cent EMS for 6 h produced more variable results as compared to 0.5 per cent, 8 h treatment. Incubation of seed in 1 per cent EMS for both 6 and 8 h was inhibitory, except to one major variation, which produced longer root and shoot as compared to the untreated seed. 1 per cent EMS resulted in more inhibitory/toxic effect on germination of guar. The concentration of 1 per cent EMS was not found to be suitable for inducing mutagenic effects.

SUMMARY

An experiment was carried out during 2009-12 to study the impact of different nutrient sources on
yield and quality of lucerne (CO 1). The mean of three years data showed that poultry manure (PM) applied @ 2.1 t/ha+398 kg rock phosphate+2 kg rhizobium+2 kg phosphobacteria recorded statistically higher green fodder yield of 60.5 t/ha/year. Highest crude protein yield (3.46 t/ha) was observed in PM treatment, but the FYM recorded higher crude protein content (24.3%). The higher nutrient uptake was recorded in organics applied treatment rather than inorganics. The INM applied soil recorded higher SOC of 0.80 per cent. The same treatment recorded higher available N, P and K content. Though inorganics recorded higher net returns, among the organics the PM applied plot recorded net returns of Rs. 95,865 with high B/C ratio of 3.7.

SUMMARY

A field experiment was conducted at CCS Haryana Agricultural University, Hisar (Haryana) during winter season (rabi) of 2014-15 to study the response of different nitrogen levels on the yield and quality of oat (Avena sativa L.) genotypes. Twelve oat genotypes viz., RSO 60, RSO 59, SKO 190, UPO 12-1, OS 405, JHO 2012-1, OL 1760, JO 04-14, JHO 2012-2, OL 125, OS 6 and Kent were sown with 40, 80 and 120 kg nitrogen per hectare. Among genotypes, OS 405 produced the maximum plant height, green fodder, dry matter followed by SKO 190. Both these two genotypes of oat remained on a par with each other with respect to green fodder and dry matter production. Genotype SKO 190 produced maximum number of tillers/metre row length which was significantly higher over rest of the genotypes. Kent was found superior in terms of crude protein content (11.36%), while SKO 190 yielded the highest crude protein yield. Growth parameters, green fodder and dry matter were influenced significantly by increasing levels of nitrogen from 40 to 120 kg/ha. Whereas leaf : stem ratio and tillers/metre row length were increased up to 80 kg N/ ha. Crude protein content and its yield revealed increased trend with increasing levels of nitrogen, maximum with 120 kg N/ha. Among genotypes, the maximum gross returns (Rs. 69645/ha), net returns (Rs. 41955/ha) and B : C ratio (1.52) were recorded with OS 405 and among different nitrogen levels, the maximum gross returns (Rs. 69945/ha), net returns (Rs. 41785/ha) and B : C ratio (1.48) were noticed with application of 120 kg N/ha.

SUMMARY

Eighteen chickpea (Cicer arietinum L.) genotypes were evaluated for yield and their susceptibility
reaction against gram pod borer, Helicoverpa armigera Hub. for three consecutive years under natural field conditions during rabi 2010-11, 2011-12 and 2012-13 at Hisar. Among these, maximum grain yield was realized from the genotype H 04-28 (13.00 q/ha) during the season rabi 2010-11 and it was statistically at par with RSG 931 (12.45 q/ha), H 03-56 (11.73 q/ha) and RSG 963 (10.82 q/ha) during rabi 2011-12 and it was statistically at par with GNG 1488 (10.01 q/ha), CSJ 140 (9.07 q/ha) and H 03-56 (8.95 q/ha) during Rabi 2012-13 and it was statistically at par with RSG 888 (8.80 q/ha) and GNG 1591 (7.79 q/ha). However, on the basis of average of three years (2010-11 to 2012-13), the maximum yield was exhibited by the genotype GNG 1488 (9.36 q/ha) followed by RSG 931 (8.95 q/ha), H 04-28 (8.32 q/ha) and H 03-56 (8.20 q/ha). The genotype H 03-56 flowered earliest in 68-71 days and proved the best donor against gram pod borer with PSR 4.7. Minimum
larval population was recorded in BG 256 (15.8 l/mrl) and it was followed by GL 25016 (17.5 l/mrl) and H 04-28 (18.5 l/mrl). Minimum per cent pod infestation by H. armigera was recorded in genotype H 01-27 (27.8%) and it was superior over all other genotypes. It was followed by H 03-56 (29.5%), CSJ 140 (30.9%) and GNG 1488 (31.3%). H 01-27 proved least susceptible genotype under natural field condition. The genotype H 03-56 flowered earliest and seemed to be the best as potential donor for pod borer’s tolerance under late sown condition. GNG 1488, RSG 931, H 04-28, H 03-56 and RSG 963 proved promising genotypes for yield and against H. armigera. These genotypes may further be utilized in breeding programmes to develop the high yielding and tolerant cultivars against gram pod borer.

SUMMARY

The present experiment was carried out at Research Farm, CCSHAU, Hisar during kharif 2015 to evaluate the performance of newly developed 30 genotypes of cowpea under prevailing Haryana agro-climatic conditions. Both within between group variation was studied. The group low fodder-medium grain yield had
maximum genotypes i. e. RC-101, GC-13-1, TC-142, TC-141, PGCP-11, KBC-5, GC-5, Pant lobia-3, while CP-05040, GPCP-28, PGCP-24 and GC-1105 having considerable value for grain yield. However, in low fodder-high grain yield group only one genotype i. e. PGCP-2-3 was placed. It had high value for grain production and could be utilized for cowpea grain production after testing over time and space. The medium fodder-low grain yield producing group included only six genotypes i. e. KBC-6, KBC-8, KBC-7, KBC-9, PTB-1 and DC-16 which could be utilized for further improvement of the fodder yield. However, only three genotypes, viz. KBC-5, Goa Cowpea-3 and GC-901 were included in the high fodder-low grain yield production and could be utilized for cowpea fodder production after testing over time and space. The genotype TPTC-29 was included in medium fodder-medium grain yield and one genotype (GC-1106) was included in medium fodder-high grain yield, which had excellent grain production as well as good potential for fodder production. It could be utilized for dual purpose after extensive testing over time and space.
