Field experiments were conducted for three years at Pulses and Oilseeds Research Station, Berhampore, Murshidabad, West Bengal, India during rabi 2007-08, 2008-09 and 2009-10 to study the effects of seed hydro-priming and urea spray in lentil. The experiment was laid out in a factorial randomized block design with four replications having ten treatment combinations viz. two levels of seed priming as factor A and five levels of foliar spray of 2% urea solution as factor B. Experimental results revealed that growth, yield attributing characters, yield and seed protein content of lentil were significantly influenced by seed hydro-priming, urea spray and interaction effects of these two factors. Significantly higher seed yield was obtained under the water soaking treatment (1211 kg ha-1) as compared to no soaking (1169 kg ha-1). Among the foliar spray treatments, two sprays at branching and pod initiation stages recorded the highest seed yield (1271 kg ha-1) of lentil cultivar WBL-58 followed by one spray at flower initiation stage (1236 kg ha-1) irrespective of seed priming. Among the interaction effects, two sprays at branching and pod initiation along with water soaking recorded the highest seed yield (1295 kg ha-1) followed by one spray at flower initiation along with water soaking (1265 kg ha-1). Seed hydro-priming and urea spray were found to increase the seed yield of lentil to the tune of 17.9 % and seed protein content by 19% over their non application.

ABSTRACT A factorial based on RCBD experiment was conducted to evaluate the effects of priming and foliar spray of cycocel on rapeseed yield components. Treatments were included; seed priming (0, 600, 900, 1200, 1500 μM) and foliar spray (0, 600, 1200 μM) with cycocel at development stage of flower buds. The results revealed that seed priming with cycocel significantly increased emerged plant number per plot, silique dry weight in the main stems and branches, plant dry weight, branches number, silique number in the main stems and branches, seed number in branches, 1000 seeds weight, and seed yield in non-stress conditions. Foliar application with cycocel also increased plant dry weight, 1000 seeds weight in branches, harvest index and seed yield. Moreover, interaction effect of priming and foliar application of cycocel increased plant dry weight and 1000 seeds weight with branches. CCC foliar application during the early stages of reproductive stage went to elevated plant dry weight and 1000 seeds weight in auxiliary branches and, also increased harvest index and grain yield. Mean comparison and interaction effects of traits also revealed that, appropriate levels of CCC had the meaningful effects on any agronomic and physiological trait. However, the most meaningful impact in most traits was traced in case with primed seed with 900 and 1500 μM CCC. Overall, owing to the present data, CCC priming under both normal and harsh conditions may raise the germination related traits, seedling establishment, plant growth and ultimately may goes to increased yield.

A field experiment was performed at Agricultural College, Bapatla, ANGRAU, Guntur during kharif season of 2020 to evaluate the efficacy of zinc nutrition on quality, yield and economics of sweetcorn. Experiment was carried out in Randomized Block Design and comprising of nine treatments with three replications. The results disclosed that application of recommended dose of fertilizers along with soil application of 10 kg ha-1 Zn EDTA + two foliar sprays of nano zinc @ 250 ppm at 20 & 40 DAS registered remarkably higher protein content (12.98%) and zinc content (34.59 ppm) in kernel which was considered to be superior over the remaining zinc management practices tried. Also, highest green cob (12,638 kg ha-1), green fodder (19,674 kg ha-1), stover yield (7,590 kg ha-1) and gross returns (₹ 1,93,360 ha-1) was recorded from the treatment with soil application of Zn EDTA @ 10 kg ha-1 + two foliar sprays of nano zinc @ 250 ppm at 20 & 40 DAS along with RDF over control. However, highest net returns (₹ 1,38,664 ha-1) and benefit cost ratio (2.74) was recorded with RDF + ZnSO4 @ 25 kg ha-1 (Soil) + Nano ZnO @ 250 ppm at 20 and 40 DAS (Foliar spray). The effectiveness of Zn EDTA compared to ZnSO4 is responsible for the higher quality parameters and yield of sweetcorn but due to its higher cost, Net returns and B;C ratio are maximum for the plots treated with ZnSO4 making it more economically viable.

An experiment was conducted to study the effect of micronutrients on the growth and yield performance of chickpea. The experiment was consisted using two factors- variety and treatments. Two local cultivars viz. BARI Chola-5 and BARI Chola-9 and five treatments e.g. T0 = control, T1 = 2 kg B/ha, T2 = 2 kg Mo/ha, T3= seed priming with Mo (1g/l water), T4 = foliar spray of B (0.5 g/l water) + seed priming with Mo (1g/l water), and T5 = 2 kg B/ha + seed priming with Mo (1g/l water) were considered for this study. A randomized complete block design (RCBD) was adopted with three replications. Significant variation was observed between the varieties and here the BARI Chola-9 produced the higher seed yield (2.47 ton/ ha). Treatment showed significant effect on the yield attributes and yield of chickpea. The highest plant height, number of branches/ plant, number of pods/ plant, nodule/ plant, number of effective pod/ plant, length of the pod, 1000-grain weight, seed yield, straw yield, biological yield was obtained from T4. The highest seed yield (2.68 ton/ ha) was recorded from BARI Chola-9 with foliar spray of boron and seed priming with Mo. The results indicated that foliar spray of B and seed priming with molybdenum can be beneficial in improving growth and yield of chickpea variety BARI Chola-9. J.

Background: Pulses are wonderful gift of the nature to agriculture. They provide nutrition to human beings and animals as food and feed respectively. Among the pulses, chickpea is an important rabi season crop with high acceptability and wider use in nutritional food basket. A field experiment was carried out on medium black calcareous soil at Junagadh Agricultural University, Junagadh, Gujarat during rabi season 2017-18 under saurastra condition to evaluate agronomic biofortification of zinc in chickpea (Cicer arietinum L.) varieties through seed, soil and foliar application. Methods: The experiment was laid out in factorial randomized block design with three replications. The treatment combinations comprised two varieties viz., GG 1 (V1) and GJG 3 (V2) and six zinc fortification treatments viz., control, seed treatment ZnSO4 @ 3 g kg-1 seed, 0.5% ZnSO4 foliar spray, seed treatment ZnSO4 @ 3g kg-1 seed + 0.5% ZnSO4 foliar spray, soil application ZnSO4 @ 25 kg ha-1 and soil application ZnSO4 @ 25 kg ha-1 + 0.5% ZnSO4 foliar spray. The chickpea was grown with standard package of practices. Result: The results revealed that a significant improvement in 100-seed weight, seed yield, stover yield and biological yield were observed with chickpea variety GJG 3 over GG 1. Significantly higher numbers of pods per plant (45.83) was recorded with variety GG 1. Significantly, chickpea variety GJG 3 was found superior in zinc content and uptake in seed and stover. Under agronomic strategy, zinc fortification through soil application ZnSO4 @ 25 kg ha-1 + 0.5% ZnSO4 foliar spray at flowering and pod filling stages significantly improved yield attribute and yield viz., pods per plant (55.17), seed yield (2288 kg ha-1) and stover yield (3553 kg ha-1) and quality parameters viz., protein content in seed (22.89%) and protein yield (523 kg ha-1), zinc content and uptake in seed and stover (45.98 and 37.51 ppm and 104.87 and 133.35 g ha-1, respectively) over all other zinc biofortification treatments.

A critical stage of the plant's life cycle is germination and insufficient seedling emergence contributes to the lower productivity of finger millet. Priming improves seedling emergence, reduces stand establishment time, and improves seedling germination. There is a need to develop a new technology like Nanotechnology that can precisely detect and deliver the right amount of nutrients or other inputs to safe crops for the environment and maximising productivity. A field experiment was conducted during Kharif season to evaluate the response of effective farming practice for sole finger millet + greengram intercropping system under rainfed conditions to varied levels of bio-seed priming and foliar application of nanoparticles on crop growth and productivity. The results of the experiment revealed that finger millet (Eleusine coracana) intercropped with greengram (Vigna radiata) (2:1) had a significant level (<0.05) increase in growth and yield parameter of finger millet compared to sole finger millet. Application of Prosopis juliflora leaf extract 1 per cent alone + Foliar ZnO nanoparticle @ 500 ppm showed a significant level (<0.05) increase in growth and yield parameter like grain yield (3238.84 kg ha-1), finger millet equivalent yield (FMEY) (3483.84 kg ha-1) and straw yield (7393.83 kg ha-1) compared to Pogamia pinnata leaf extract 1% alone + Foliar ZnO nanoparticle @ 500 ppm. The present study mainly focussed on cropping system, bio seed priming, and foliar application of nano zinc oxide utilized during rainfed conditions to increase uniform germination, drought resistance and improve crop yield along with nutrient content in seeds.

Abstract Niger (Guizotia abyssinica Cass.) is an important minor oil seed crop grown in dry areas grown mostly by tribal and interior places as life line of tribal segment. Tribal people mainly use its oil for cooking purpose, above than that there were also other uses. Hence, the niger crop should be protected from the infection. The crop is affected by number of fungal diseases. Therefore, a field experiment was formulated for three years with the four replications at the Niger Research Station (NRS) at Navsari Agricultural University (NAU), Vanarasi, Navsari (Gujarat) on the foliar diseases of GN-1 variety of niger crop. In this experiment, six different fungicides along with one control have been evaluated to control the Alternaria and Cercospora leaf spot diseases, out of which all the fungicidal treatments were significantly superior over the control. Here, foliar spray on the incidence of diseases was compared with the control (without any treatment). All the fungicidal treatments were significantly superior over the control to reduce Alternaria and Cercospora leaf spot diseases of Niger crop. Treatment of Carbendazim + Mancozeb (0.2 %) with two sprays first from the initiation of the disease and second after the interval of 15 days recorded the lowest incidence of Alternaria (14.56) and Cercospora (14.94) leaf spot diseases of niger and recorded the highest seed yield 337 seed yield kg/ha along with the net return with cost benefit ratio graph.
