The mustard production and productivity of the hot arid region of Rajasthan is dominated by both genetic makeup and environmental conditions. An experiment was conducted with four mustard varieties  (RGN-73, RGN-229, RH-30 and Pusa bold) in two growing environments (open environment and neem shade). Pusa bold gave significantly higher plant height than other varieties. Among varieties, RGN-73 had significantly higher number of branches per plant, dry matter accumulation per plant, siliquae per plant, seed yield, stover yield, biological yield, harvest index and heat use efficiency than other varieties. However, significantly higher test weight was in Pusa bold variety. Under open environment condition, significantly higher growth, yield attributes, yield, harvest index and heat use efficiency were found as compared to neem shade environment. The results revealed that variety RGN-229 took more days for completion of life cycle as compared to other varieties, hence RGN-229 variety required significantly more degree days than other varieties. The pheno-thermal index was significantly higher in open condition.

AbstractHigher demands of food led to higher nitrogen application to promote cropping intensification and produce more which may have negative effects on the environment and lead to pollution. While sustainable wheat production is under threat due to low soil fertility and organic matter due to nutrient degradation at high temperatures in the region. The current research explores the effects of different types of coated urea fertilizers and their rates on wheat crop under arid climatic conditions of Pakistan. Enhancing nitrogen use efficiency by using eco-friendly coated urea products could benefit growers and reduce environmental negative effects. A trial treatment included N rates (130, 117, 104, and 94 kg ha-1) and coated urea sources (neem coated, sulfur coated, bioactive sulfur coated) applied with equal quantity following split application method at sowing, 20 and 60 days after sowing (DAS). The research was arranged in a split-plot design with randomized complete block design had three replicates. Data revealed that bioactive sulfur coated urea with the application of 130 kg N ha-1 increased chlorophyll contents 55.0 (unit value), net leaf photosynthetic rate (12.51 μmol CO2 m-2 s-1), and leaf area index (5.67) significantly. Furthermore, research elucidates that bioactive sulfur urea with the same N increased partial factor productivity (43.85 Kg grain Kg-1 N supplied), nitrogen harvest index (NHI) 64.70%, and partial nutrient balance (1.41 Kg grain N content Kg-1 N supplied). The neem-coated and sulfur-coated fertilizers also showed better results than monotypic urea. The wheat growth and phenology significantly improved by using coated fertilizers. The crop reached maturity earlier with the application of bioactive sulfur-coated urea than others. Maximum total dry matter 14402 (kg ha-1) recorded with 130 kg N ha-1application. Higher 1000-grain weight (33.66 g), more number of grains per spike (53.67), grain yield (4457 kg ha-1), and harvest index (34.29%) were obtained with optimum N application 130 kg ha-1 (recommended). There is a significant correlation observed for growth, yield, and physiological parameters with N in the soil while nitrogen-related indices are also positively correlated. The major problem of groundwater contamination with nitrate leaching is also reduced by using coated fertilizers. Minimum nitrate concentration (7.37 and 8.77 kg ha-1) was observed with the application of bioactive sulfur-coated and sulfur-coated urea with lower N (94 kg ha-1), respectively. The bioactive sulfur-coated urea with the application of 130 kg N ha-1 showed maximum phosphorus 5.45 mg kg-1 and potassium 100.67 mg kg-1 in the soil. Maximum nitrogen uptake (88.20 kg ha-1) is showed by bioactive sulfur coated urea with 130 kg N ha-1 application. The total available NPK concentrations in soil showed a significant correlation with physiological attributes; grain yield; harvest index; and nitrogen use efficiency components, i.e., partial factor productivity, partial nutrient balance, and nitrogen harvest index. This research reveals that coating urea with secondary nutrients, neem oil, and microbes are highly effective techniques for enhancing fertilizer use efficiency and wheat production in calcareous soils and reduced N losses under arid environments.

The climate of the terai region of West Bengal, India in general, is subtropical par humid to tropical with light textured acid soil with the problems like low moisture retention, low water use efficiency, leaching of bases, soil erosion, limited availability of multiple plant nutrients and restricted activity of beneficial soil micro-organisms. To combat these soil health related problems and to improve the overall productivity of North Bengal, a comparison between the conventional and conservation tillage was taken up and the immediate results were measured in terms of growth, yield attributes and yield. In the first two years of experimentation, though different growth attributes, grain yield, stover yield, and different yield attributing characters such as kernel rows cob-1, number of kernels row-1, 100 seed weight (g), number of seeds cob-1, girth of cob, length of cob and number of effective cob plant-1 were higher in conventional tillage as compared to conservation tillage but in terms of soil heath characteristics, conservation tillage had a meaningful remark from the initial years towards the future food security. Mulching @ 4 t ha-1 was found to have performed better than unmulched treatments. Application of 75% recommended dose of fertilizer + Vermicompost @ 10 t ha-1 resulted in better growth and yield attributes which directly influenced to have higher grain and stover yield.

Background: Among pulses, blackgram is one of most important crop. Blackgram has originated from Indian sub-continent where it has been cultivated from ancient times and standout amongst most expensive pulse crop in India. Being observed, the productivity of blackgram is low in India as well as in Punjab due to lack of knowledge regarding various agronomic implementations, among them, time of sowing and selection of suitable cultivar are one of the major limiting factors in production, especially during kharif season. Methods: The research was carried out to investigate the effect of different dates of sowing on growth, yield attributes and yield of various cultivars of kharif blackgram (Vigna mungo L.) during kharif season 2019 at Student’s Research Farm, Department of Agriculture, Khalsa College, Amritsar. The experiment was laid-out in split-plot design, consisting of four dates of sowing (8th July, 18th July, 28th July and 8th August) as main-plot treatments and three cultivars (Mash114, Mash 338 and KUG 479) as sub-plot treatments, with four replications. Result: Among the sowing dates, the higher seed yield (10.27 q/ha) of blackgram was recorded when crop was raised on 8th July, which was significantly 12.6%, 20.3% and 30.5% higher than 18th July, 28th July and 8th August sown crop respectively. Among blackgram cultivars, the higher seed yield was observed in Mash 114 (10.19 q/ha) which was significantly 14% and 32% superior over Mash 338 and KUG 479 respectively. The sowing dates and cultivars had significant effect on the pods/plant, seeds/pod and seed weight/plant. The significantly higher number of pods/plant (24.3), seeds/pod (6.8) and seed weight/plant (3.2 g) were obtained with 8th July sown crop as compared to 28th July and 8th August sown crop. Among the cultivars, the significantly higher number of pods/plant (23.6), seeds/pod (6.4) and seed weight/plant (3.2 g) were recorded with Mash 114. The growth parameters viz. Plant height, nodules/plant, leaf area index and dry matter accumulation, were shown decreased trend by 29.2%, 19.13%, 12.2% and 25.4% respectively with the delay in sowing from 8th July to 8th August.

A field experiment was carried out during summer season of 2018 at Instructional Farm, Jaguli, BCKV, West Bengal to study the effect of integrated nutrient management on growth, yield and economics in hybrid maize. The treatments were T1-100% RDF (150:75:75 kg/ha N, P2O5 and K2O) (control), T2- 75% RDF+ Vermicompost @ 2t/ha, T3-75% RDF+ Yeast Vinasse @ 2t/ha, T4-75% RDF+ Vermicompost @ 2t/ha+ soil application of ZnSO4 @ 25 kg/ha, T5-75% RDF+ Yeast Vinasse @ 2t/ha+ soil application of ZnSO4 @ 25 kg/ha, T6-75% RDF+ Vermicompost @ 2t/ha+ Foliar application of ZnSO4 @ 0.5% and T7-75% RDF+ Yeast Vinasse @ 2t/ha+ Foliar application of ZnSO4 @ 0.5% replicated thrice in RBD. The result of the experiment revealed that application of vermicompost @ 2 t/ha along with 75% RDF and 0.5% foliar application of ZnSO4 (T6) exhibited maximum plant height (250.97 cm), LAI (4.58), dry matter accumulation (1680.38 g/m2), number of grains/cob (402.64), cob length (22.34 cm), grain yield (9.04 t/ha), stover yield (13.50 t/ha), net return (Rs.77112/ha), BCR (2.33) and uptake of N, P2O5 and K2O (200.54, 66.45 and 119.12 kg/ha respectively) over application of 100% RDF. However, T6 was statistically at par with the T4 and T7, which produced 8.94 and 8.75 t/ha grains respectively. Therefore, the study concluded that integrated application of vermicompost @ 2 t/ha along with 75% RDF and 0.5% foliar application of ZnSO4 can be recommended for better grain yield and higher profit of summer maize.

A field experiment on rice (Oryza sativa L.) crop was conducted at Rice Research Station, Kaul (Kaithal), India during kharif season of 2017 and 2018 to evaluate the optimum schedule of nitrogen application in the rice grown under early and late planting conditions. The treatments consisted of three timings of transplanting (3rd week of June, 1st week of July and 3 rd week of July), four levels of N (90, 120, 150 and 180 kg Nha-1) and four timings of N fertilizer application (½ at transplanting + ½ at 21 DAT, ½ at 21 DAT + ½ at 42 DAT, 1/3 at transplanting + 1/3 at 21 DAT + 1/3 at 42 DAT and LCC based N supply) and were laid out in split-plot design with transplanting time and N levels in main plots and N application time in sub-plots. The growth parameters (plant height, number of tillers/m2 and dry matter accumulation/m2), yield attributing characters (number of panicles/m2 and grains/panicle) and yield (grain and straw yield) of rice crop reduced significantly under late planting (3rd week of July) as compared to that under the two earlier plantings (3rd week of June and 1stweek of July) whereas the two earlier plantings were at par in respect of these parameters. The growth, yield attributes and the yield increased with every increase in N application rates but the increase was significant up to 150 kg Nha-1. The highest yield was (7.33 tha-1), however, obtained with the crop transplanted early (up to1st week of July) and supplied with 150 kg Nha-1.Application of N in three equal splits (at 0, 21 and 42 DAT or as per LCC schedule), being at par, resulted into higher yield (grain and straw) than the N application in two equal splits. The net returns and B: C ratio increased appreciably with increase in N application levels upto 150 kg Nha-1 obviously due to increase in crop yield.

The yield loss as a result of weed infestation is a major problem in maize fields. Hence, this research meant to examine the impacts of weed chemical control on maize growth and yield. The design of experiment was randomized complete block, and comprised 10 treatments viz., T1 (Control, weedy check), T2 (Weed free), T3 (Atrazine 1.5 kg ha-1 pre-emergence), T4 (Atrazine 750 g ha-1 + Pendimethalin 750 ml ha-1 pre-emergence), T5 (Atrazine 1.5 kg ha-1 followed by 2,4-D amine 0.4 kg ha-1 at 25 days after sowing as Post-emergence), T6 (Halosulfuron 67 g ha-1 at 25 DAS), T7 (Atrazine 1.5 kg ha-1 pre-emergence followed by Halosulfuron 90 g ha-1 25 days after sowing), T8 (Tembotrione 120 g ha-1 Post-emergence at 25 days after sowing), T9 (Pendimethalin 1000 ml ha-1 pre-rise fb Atrazine 750 g ha-1 + 2,4-D amine 0.4 kg ha-1 at 25 days after sowing as Post-emergence) and T10 (Atrazine 1.5 kg ha-1 pre-emergence followed by Tembotrione 120 g ha-1 Post-emergence at 25 days after sowing) with 3 replicates. The results showed that among other treatments, T10 recorded highest number of kernels per row (36.18), number of kernel cob-1 (499.12) and kernel weight cob-1 (136.97 g). A higher plant height (172.19 cm), leaf area (396.6 cm2 plant-1), dry matter accumulation (211.37 g plant-1), kernel yield (6.7 t ha-1) and stover yield (11.6 t ha-1) were found with weed free check plot which is on par with T10 treatment which brought about a higher value of plant height (162.93 cm), dry weight accumulation (205.7 g plant-1), leaf area (384.3 cm2 plant-1), kernel yield (6.5 t ha-1) and stover yield (11.4 t ha-1). In the meantime, T9 treatment reasonably increased kernel yield (6.2 t ha-1) and stover yield (11.0 t ha-1). It shows that application of herbicides as pre-emergence followed by post-emergence, such as T10 treatment could be a good method for weed control in maize fields.
