SUMMARY

Field experiment was conducted during kharif season of 2019 at Department of Livestock Farm Complex, Veterinary College, Shivamogga. The experiment was laid out in a randomized complete block design with thirteen treatments having three replications. During the experiment, three hybrid napier cultivars, i.e., Dharwad Hybrid Napier-6, CO-5 and Taiwan Super Napier-1 & three fodder cowpea genotypes, i.e., Cowpea local, MFC-09-1 and MFC-08-14 were used. Fodder cowpea genotypes were tested as an intercrop in different hybrid napier cultivars under normal spacing and paired row. Combinations of hybrid napier cultivar Taiwan Super Napier-1 with fodder cowpea improved genotypes (MFC-08-14 and MFC-09-1) in paired row performed better and found significantly superior over cultivar Dharwad Hybrid Napier-6 with different genotypes of fodder cowpea. The combination registered higher plant height (373 cm), number of tillers/plant (73.67) and number of leaves/plant (434.67), green fodder yield (321.21 t/ha), dry fodder yield (66.09 t/ha) and per plant yield (17.35 kg). This was closely followed by hybrid napier cultivar CO-5 with fodder cowpea improved genotypes. Different genotypes of fodder cowpea did not differ in green and dry fodder yields but normal planting resulted maximum tonnage of green and dry fodder (7-8 and around 1.5 t/ha, respectively) compared to paired row system (5-6 and around 1.0 t/ha) due to difference in population.

SUMMARY

Seventy-three sorghum genotypes were evaluated under six field trials for resistance against shoot fly and spotted stem borer along with commercial, resistant, susceptible and local checks at Hisar during Kharif, 2018. Per cent deadhearts caused by shoot fly and stem borer were recorded at 28 and 45 days after emergence, respectively under natural field conditions. Sixteen genotypes viz. SPH 1906, SPV 2581, SPV 2586, SPV 2594, SPV 2530, SPV 2531, SPV2597, SPV 2598, SPV 2604, SPV 2521, AKSV 425, RBSV 34, RBSV 36, SFRM 1, SFRM 2, SFRM 3 and SFRM 4 exhibited resistance against shoot fly as these genotypes produced less than 45 per cent deadhearts caused by Atherigona soccata. However, the genotype SFRM 1 exhibited resistance against both pests including A. soccata and Chilo partellus under natural field conditions.

SUMMARY

A field experiment entitled “Improving fodder quality through inclusion of legume in different grass based intercropping systems” was conducted at Research Farm, Department of Agronomy, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur, Madhya Pradesh during 2018-19 to 2019-20, both consecutive year with eight grass based cropping systems. The recommended dose of fertilizer 150 kg N, 80 kg P₂O₅ and 40 kg K₂O/ha was applied through urea, single super phosphate and muriate of potash. Among the different grass based cropping systems pearlmillet napier hybrid sole crop was exhibit significantly higher dry fodder yield (39.63 and 40.75 t/ha) over the guinea grass (GG) sole cropping (22.92 and 23.42 t/ha) during both the year respectively. Highest crude protein yield was in pearlmillet napier hybrid sole cropping (4.93 and 5.08 t/ha) significantly superior to the guinea grass sole cropping (2.27 and 2.32 t/ha) during both the year respectively. Maximum crude yield (12.05 and 12.41 t/ha) were under pearlmillet napier hybrid sole cropping and significantly superior over GG in paired rows + Sesbania grandiflora (5.79 and 6.00 t/ha) during both the year respectively.

SUMMARY

A field experiment was conducted at Ram Dhan Singh Seed Farm, CCS Haryana Agricultural University, Hisar (Haryana) to evaluate the response of zero-till rainfed maize to super absorbent polymer and mulching in maize-wheat cropping system under semi-arid conditions. The experiment was laid out in a split-plot design with combination of two levels of tillage practice (conventional and zero tillage) and two levels of mulch application (without mulching and mulching @ 4 tonnes/ha) in main plots and 3 levels of hydrogel (No hydrogel, hydrogel @ 2.5 kg/ha, hydrogel @ 5.0 kg/ha) in sub-plots with three replications. The soil of the experimental field low in available nitrogen, medium available P and high in available K. Among the tillage practices, zero till sown maize crop recorded higher grain yield (5466 kg/ha), water use efficiency (23.5 kg/ha-mm) and benefit cost ratio (3.98) as compared to the maize crop sown after conventional tillage. Among the mulching levels, mulching @ 4 t/ha in maize crop recorded higher grain yield (5058 kg/ha), water use efficiency (21.7 kg/ha-mm) and benefit cost ratio (3.02) as compared to the maize crop without mulching. Among the hydrogel levels, the maximum grain yield (4921 kg/ha), was produced by application of hydrogel @ 5.0 kg/ha, which was significantly superior to no hydrogel, but statistically at par to hydrogel @ 2.5 kg/ha. Net returns was achieved maximum with application hydrogel @ 2.5 kg/ha, but the benefit cost ratio decreased with hydrogel application. Maximum grain yield (5546 kg/ha) was obtained in zero tillage with mulch/residue retention @ 4 t/ha.The grain yield of succeeding wheat was not influenced markedly by the tillage practices, mulching and hydrogel application in maize. System maize equivalent followed the trend as per grain yield of maize.

SUMMARY

A field experiment was conducted during kharif and rabi seasons of 2019-20 at Zonal Agricultural Research Station, Vishweswaraiah Canal Farm, Mandya, Karnataka to study the effect of different organic sources of nutrients on production potential and profitability of fodder maize-cowpea cropping system. The experiment was laid out in a randomized complete block design with ten treatments comprising different organic sources of nutrients and replicated thrice. The data revealed that, application of 50% RDN through FYM and remaining 50% RDN through poultry manure as top dress at 30 DAS resulted higher green fodder yield (424.13 and 188.67 q/ha) and dry matter yield (117.13 and 40.18 q/ha) both in fodder maize and succeeding fodder cowpea, respectively. The same combination of organic nutrients sources also recorded higher nitrogen (217.03 and 111.25 kg/ha), phosphorus (21.17 and 6.82 kg/ha) and potassium uptake (208.14 and 69.79 kg/ha) at harvest and also found profitable with higher net returns (Rs. 53043/ha and Rs. 24104/ha) and benefit cost ratio (2.67 and 2.05) both in fodder maize and succeeding fodder cowpea, respectively.

SUMMARY

Present investigation was conducted during Rabi season 2018-19 at Research Area of CCS Haryana Agricultural University, Hisar. The experiment was comprised of three cutting schedules viz. 45, 55 and 65 days after sowing (DAS) as main plot treatments and six nitrogen schedules i.e. N₁– 1/3 basal +1/3 at first irrigation and 1/3 after cut, N₂– ½ basal + ½ at first irrigation, N₃-½ basal and ½ after cut, N₄– ¼ basal +½ at first irrigation and ¼ after cut, N₅ – ½ basal +¼ at first irrigation and ¼ after cut, N₆ – ¼ basal +¼ at first irrigation and ½ after cut as sub plot treatments. Experiment was laid out in split plot design with four replications. Among different cutting schedules, maximum plant height (65.6cm), dry matter accumulation (76.9g) and green fodder yield (247.98 q/ha) were recorded when crop was cut at 65 DAS for green fodder as compared to rest of the cutting schedules. Whereas, crop cut at 45 DAS for green fodder then left for grain produced maximum grain yield (61.36 q/ha), which was significantly higher than cut at 55 DAS and 65 DAS. Among different nitrogen schedule, at the time of cut, N₂ resulted in significantly taller plants (53.3 cm) and maximum dry matter (63.1 g). Maximum green fodder yield (177.85 q/ha) was recorded when full nitrogen dose was applied before cutting (N₂). Whereas, maximum grain yield (56.88 q/ha) was recorded in N₃, which was significantly higher than treatment N₂ and N₅ but it was at par with in N₁, N₄ and N₆.
