    Influence of Iron and Zinc Fortified with Organics in Rabi Sorghum
    (University of Agricultural Science, Dharwad, 2017-08) Anilkumar A.H.; Kubsad, V.S.
    A field experiment to study the effect of iron and zinc fortified with organics in rabi sorghum under rainfed condition on clay loam soil was conducted at the Main Agricultural Research Station, University of Agricultural Sciences, Dharwad (Karnataka) during rabi 2016. The experiment consisting of eleven treatments with varied levels of FeSO4 and ZnSO4 was laid out in randomized complete block design with three replications. Soil application of RDF + Enriched FYM [(50 kg FYM ha-1 + 3.75 kg ZnSO4 ha-1) + (50 kg FYM ha-1 + 3.75 kg FeSO4 ha-1)] recorded significantly higher total dry matter production (193.61 g plant 1), grain weight (62.33 g plant-1), test weight (37.77 g), grain yield (4,287 kg ha-1), fodder yield (7.51 t ha-1), net returns ( 85,702 ha 1) and benefit cost ratio (3.50) over control, recommended dose of fertilizer and recommended package of practice. Soil application of RDF + Enriched vermicompost [(50 kg vermicompost ha-1 + 15 kg ZnSO4 ha-1) + (50 kg vermicompost ha-1 + 15 kg FeSO4 ha-1)] recorded significantly higher iron content in both grain (39.52 mg kg 1) and fodder (42.34 mg kg 1) which was 13.4 and 15.8 per cent increase over control, 12.6 and 13.8 per cent increase over recommended dose of fertilizer, 9.4 and 9.4 per cent increase over recommended package of practice. Similarly, zinc content in grain and fodder was significantly higher with the same treatment (28.44 and 29.44 mg kg-1, respectively) which was 13.5 and 16.0 per cent increase over control, 12.2 and 14.5 per cent increase over recommended dose of fertilizer, 7.4 and 5.6 per cent increase over recommended package of practice respectively. Soil application of RDF + Enriched FYM with ZnSO4 and FeSO4 each @ 3.75 kg ha-1 gives higher yields, with higher iron and zinc content.

    (University of Agricultural Science, Dharwad, 2016-06) Yogikoppa, Shruti M.; Aladakatti, Y.R.
    A field experiment was conducted in medium deep black soils to assess the optimum drip irrigation regimes and fertigation to intra hirsutum Bt cotton and their effect on endotoxin expression. It was laid out in factorial randomised complete block design with three replications during 2015-16 at Agricultural Research Station, Dharwad. Paired sowing system with drip irrigation at 1.0 Etc recorded significantly higher seed cotton yield per ha (3,606 kg ha-1) over 0.6 Etc and furrow irrigation, but it was on par with 0.8 Etc. Fertigation with 100 per cent recommended dose (RD) N and K (150:75 kg ha-1) in six equal splits was recorded significantly higher seed cotton yield, and it was on par with fertigation 75 per cent RD N and K. The interaction effect of drip irrigating at 1.0 Etc with fertigation of 100 per cent RD N and K recorded significantly higher seed cotton yield (4,024 kg ha-1). However, it was on par with drip irrigation at 0.8 Etc with fertigation of 75 per cent RD N and K (3,943 kg ha-1). The Cry 1Ac and Cry 2Ab protein content in leaves was non-significant at all the growth stages due to irrigation levels except at 45 DAS, but different levels of nutrients had significant effect on endotoxin expression. Water use efficiency (WUE) was significantly higher with drip irrigation at 0.8 Etc level (6.76 kg ha-1-mm). Maximum WUE was recorded at 100 per cent fertigation of RD N and K and it was on par with 75 per cent fertigation of RD N and K. Significantly higher net returns (Rs 1,34,262 ha-1) and B:C (3.25) were realised with irrigating at 1.0 Etc along with fertigation of 100 per cent RD N and K in six equal splits, however it was on par with irrigation at 0.8 Etc with fertigation of 75 per cent RD N and K.

    (University of Agricultural Science, Dharwad, 2016-06) Ravikumar, H.P.; Wali, S.Y.
    A field experiment was conducted to study the response of transplanted onion to sulphur and zinc nutrition during summer season of 2015 at farmer’s field in Vijayapura district (Zone-3). The treatments comprised combinations of four sulphur levels and three zinc levels along with a RPP, RDF and farmer’s practice (control). Totally fourteen treatment combinations were tested using randomized complete block design with three replications. The results on growth parameters, yield attributing parameters (bulb weight, bulb diameter and bulb index), bulb yield, quality parameters (TSS, bulb grading and bulb dry matter), nutrient uptake and status of available nutrient content in soil revealed significant variations among sulphur and zinc levels in onion. Among the treatment combinations, the treatment which received, RPP + 40 kg sulphur ha-1 + 10 kg zinc ha-1 has recorded significantly higher plant height, leaf area plant-1, dry matter accumulation in leaf, bulb and total dry matter accumulation at different growth stages (at 30, 60, 90 DAT and at harvest), bulb weight plant-1 (110.07 g), bulb diameter (41.90 mm), bulb index (1.91) and bulb yield (406.23 q ha-1) when compared with control. The quality parameters viz., TSS (13.89 %), A, B, C grade bulbs and lowest unmarketable bulbs, higher bulb dry matter were superior over control treatment. The uptake of N, P2O5, K2O, S and Zn as well available nutrient content of S and lower availability of N and P (at harvest ) in soil were recorded significantly higher values over control. The significantly higher net returns (` 4,43,019 ha-1) and B:C (3.58) were noticed with the treatment which received RPP + 40 kg sulphur ha-1 + 10 kg zinc ha-1 as compared to control.

    (University of Agricultural Science, Dharwad, 2016-06) Lankeppanavar, Shilpa; Kubsad, V.S.
    A field experiment was conducted on intercropping of forage sweet sorghum with forage legumes (cowpea and horsegram) under different nitrogen levels at AICRP on Sorghum, MARS, Dharwad during kharif 2015. The experiment was laid out in randomized complete block design with fifteen treatment combinations consisting of sole and intercropping systems and two nitrogen levels and three replications. Significantly higher sorghum green and dry forage yield (47.25 and 12.80 t ha-1 respectively) was recorded in sole forage sweet sorghum with 100 % RDN. Among the intercropping systems, sweet sorghum + horsegram (2:1) with 100 % RDN recorded significantly higher sorghum green and dry forage yield (42.36 and 12.80 t ha-1 respectively). Among the legumes, significantly higher green and dry forage yield (25.28 and 4.93 t ha-1 respectively) was recorded in sole forage cowpea with 100 % RDN. In intercropping systems, sweet sorghum + cowpea (2:2) with 100 % RDN recoded significantly higher green and dry legume forage yield (15.51 and 3.03 t ha-1 respectively). These yield advantages are due to better growth and yield attributes. Sweet sorghum + horsegram (2:1) with 100 % RDN recorded significantly higher total green and dry forage yield (49.08 and 12.81 t ha-1 respectively) and LER (1.36). The forage quality parameters viz., crude protein (923.0 kg ha-1), crude fibre (4,216.3 kg ha-1), total ash (1,220.6 kg ha-1), ether extract (327.0 kg ha-1), nitrogen free extract (6,126.4 kg ha-1), total carbohydrates (10,342.7 kg ha-1) and organic matter (11,592.7 kg ha-1) are also significantly higher with same treatment. It also realized highest gross returns (₹ 45,519 ha-1), net returns (₹ 21,730 ha-1) and B: C ratio (1.91) as compared to others.

    (University of Agricultural Science, Dharwad, 2016-06) Prabhakar; Chandranath, H.T.
    A field experiment was conducted to study the optimum row proportion, optimum sowing time of maize and economics of maize with field pea intercropping system. It was laid out in RCBD with three replications during kharif 2015 at farmer’s field in Lokur, village Dharwad district of Karnataka. There were nine treatments consisting of two planting patterns i.e., sowing of maize within and between the rows of maize in field pea with four dates of sowing for maize. Simultaneous sowing of maize with field pea recorded significantly higher grain yield (4,459 kg ha 1) and stover yield (6,481 kg ha 1) compared to other intercropping treatments and was on par with when maize sown between the rows one week after sowing of field pea (4,297 kg ha 1). Higher maize equivalent yield (5,896 kg ha 1) and land equivalent ratio (1.23) was recorded when maize sown between the rows two weeks after sowing of field pea and was on par with sowing between rows simultaneously and one week after sowing of field pea in maize with field pea intercropping treatments. Whereas, sole maize realised higher grain yield (4,719 kg ha 1) and stover yield (6,738 kg ha 1). Among the intercropping treatments, when maize was sown between the rows three weeks after sowing of field pea recorded higher green pod yield (1,592 kg ha-1) compared to other intercropping treatments and was on par with maize sown between the rows two weeks after sowing of field pea (1,569 kg ha 1). However, sole field pea recorded significantly higher green pod yield (3,321 kg ha 1). Significantly higher net returns (` 47,636) and B:C ratio (2.36) were realised when maize was sown two weeks after sowing of field pea compared to other intercropping treatments except maize when sown between the rows simultaneously and one week after sowing of field pea.

    (University of Agricultural Science, Dharwad, 2016-06) Kittur, Chetankumar N.; Guggari, A.K.
    A field experiment was conducted at College of Agriculture, Vijayapura, to study the effect of sowing time and planting geometry on growth and yield of pigeonpea under Northern Dry Zone (Zone 3) of Karnataka during 2015-16. There were 16 treatments consisting of combinations of four sowing times viz., June II fortnight, July I fortnight, July II fortnight and August I fortnight and four planting geometries viz., 90 cm x 20 cm (S1), 120 cm x 20 cm (S2), 150 cm x 20 cm (S3) and 180 cm x 20 cm (S4). The experiment was laid out in split-plot design and replicated thrice. Experiment results revealed that, different sowing times significantly influenced the growth and yield of pigeonpea. Pigeonpea sown during June II fortnight recorded significantly higher grain yield (1,311 kg ha-1) compared to pigeonpea sown during July I fortnight (1,151 kg ha-1), July II fortnight (212 kg ha-1) and August I fortnight (264 kg ha-1). Similarly, different planting geometries influenced the grain yield of pigeonpea significantly. Pigeonpea sown at planting geometry of 90 cm x 20 cm produced significantly higher grain yield (859 kg ha-1) as compared to other planting geometries, but it was on par with 120 cm x 20 cm (777 kg ha-1). Interaction effects of sowing time and planting geometries differed significantly with respect to grain yield and economics of pigeonpea. Pigeonpea sown during June II fortnight with planting geometry of 90 cm x 20 cm recorded significantly higher grain yield (1,537 kg ha-1), net returns (1,15,664 Rs ha-1) and benefit cost ratio (6.10) over other interactions, but it was on par with crop sown during same period with 120 cm x 20 cm planting geometry (1,400 kg ha-1, 1,03,304 Rs ha-1 and 5.56, respectively).

    (University of Agricultural Science, Dharwad, 2016-06) Didal, Vijay Kumar; Hallikeri, S.S.
    Field experiment was conducted during Kharif 2015 at Agricultural Research Station Arabhavi, University of Agricultural Sciences, Dharwad, to explore the effect of foliar fertilization of market available soluble fertilizers to enhance the productivity of maize (Zea mays L.). The experiment was laid out in randomized complete block design with 3 replications and 12 treatments. The treatments consist of seven market available soluble fertilizers with two concentrations sprayed at 30 and 50 DAS. Foliar applications were made in addition to recommended dose of fertilizers application. Only water spray was kept as control. The results revealed that application of potassium nitrate with 1.0 per cent foliar spray recorded significantly higher growth, growth parameters, yield, yield attributes, nutrient uptake, nutrient use efficiency (NUE) and economics of maize over control (Only water spray). Potassium nitrate with 1.0 per cent foliar spray recorded significantly higher plant height (207.7 cm), number of leaves per plant (14.7), leaf area index (5.68), total dry matter accumulation (346.4 g plant-1), cob length (17.9 cm), cob girth (5.3 cm), number of rows per cob (16.3), higher number of grains per row (41.4), number of grains per cob (674.2), weight of 100 seeds (35.5 g), shelling % (89.6 %), grain yield (9371 kg ha-1), fodder yield (135.7 q ha-1), nitrogen uptake in grain and fodder (122.1, 177.6 kg ha-1, respectively), phosphorus uptake in grain and fodder (38.0, 42.1 kg ha-1, respectively), potassium uptake in grain and fodder (76.9, 114.8 kg ha-1, respectively) and NUE (32.6 kg kg-1). Further economic analysis indicated that gross returns (` 1,35,390), net returns (` 86,312) and B:C ratio (2.8) were significantly increased with potassium nitrate with 1.0 per cent foliar spray over control (Only water spray). It was on par with 19:19:19 with 2 per cent foliar spray and mono potassium phosphate with 0.5 per cent foliar spray. Urea with 2 per cent foliar spray recorded significantly higher SPAD meter reading at 50 and 70 DAS (46.1 and 38.6, respectively) over control (F12) (37.1 and 29.9, respectively).
