The beneficial effects of manure on soil properties, growth, and crop productivity have promoted its use for replacing the application of N fertilizer. However, it is not well understood to what extent N fertilizer was able to be substituted by cow manure. Accordingly, this pot experiment aimed to compare the effect of inorganic N fertilizer application alone with that of the combined use of inorganic N fertilizer with cow manure based on the same amount of total N on growth parameters, yield attributes, and nitrogen (N) uptake of black rice. The experiment was conducted under a screen house condition in Agriculture Faculty, Bengkulu University located at 15 meters altitude above sea level during the summer season of 2015. There were six treatments viz. T1 = 100% N from urea + 0% N from cow manure (0.52 g N + 0.00 g cow manure) pot-1, T2 = 80% N from urea  + 20% N from cow manure  (0.42 g N + 9.55 g cow manure) pot-1, T3 = 60% N from urea + 40% N from cow manure (0.31 g N  + 19.10 g cow manure) pot-1, T4 = 40% N from urea + 60% N from cow manure (0.21 g N + 28.65 g cow manure) pot-1, T5 = 20% N from urea + 80% N from cow manure (0.10 g N+ 38.20 g cow manure) pot-1, and T6 = 0% N from urea + 100% N from cow manure (0.00 g N  + 47.75 g cow manure) pot-1. The amount of inorganic N fertilizer in the form of urea and cow manure applied was calculated based on the recommended rate of 115.00 kg ha-1 for N fertilizer and 10.50 ton ha-1 for cow manure. These treatments were arranged in a Completely Randomized Design and repeated three times. The results showed that the treatments significantly (P ?0.005) affected growth parameters as measured by plant height, the number of leaves, fresh shoot weight, fresh root weight, dry shoot weight, dry root weight, yield attributes as determined by the total number of tillers, the total number productive tillers, grain yield per pot, and N uptake. The highest values for all these variables were obtained in the treatment receiving recommended rate of urea only (100% N from urea + 0% N from cow manure as equivalence) and the lowest in the treatment receiving a100% N from cow manure (0% N from urea + 100% N from cow manure). However, combined treatments of cow manure and inorganic N fertilizer such as 80% N from urea  + 20% N from cow manure, 60% N from urea + 40% N from cow manure 40% N from urea + 60% N from cow manure showed a parity statistically with the treatment receiving 100% N from urea only in maintaining the values for all these variables. Overall, the combined use of inorganic N fertilizer (urea) and cow manure as an equivalence promoted growth and yield of black rice by improving N uptake. Keywords: integrated nutrient management, soil chemical property, Nitrogen uptake, combined fertilizer application, black rice

An experiment was conducted with the objective of understanding the response of pigeonpea varieties to N levels under different method of planting. It consisted of 16 treatments with four methods of planting in main plots, two varieties and two N levels in double split plot (DSP) design. The results of pooled data indicated that significantly higher plant population (50,683 ha-1) and seed yield (1255 kg ha-1) besides lower cost of cultivation (Rs. 27,875 ha-1), higher net returns (Rs. 33,698 ha-1) and B:C ratio (2.19) were recorded with normal planting (90x20 cm) compared to other planting methods. Transplanted pigeonpea (120x90 cm) had significantly higher stem girth (10.32 cm) and number of pods plant-1 (1483) besides on par seed yield (1100 kg ha-1) with that of normal planting. However, the yield improvement is not substantial to offset the additional costs involved in nursery raising and transplanting. Though the performance of transplanted pigeonpea (90x90 cm) and dibbling (90x90 cm) was similar with regard to seed yield, dibbling fared well with regard to net returns and B:C ratio. PRG-158 variety accrued an additional net returns of Rs. 2340 ha-1 over Asha, due to its short duration. N doses didn’t differ significantly in respect of growth parameters, yield attributes and yield. Thus, normal planting method (90x20 cm) with PRG-158 variety and 20 kg N ha-1 can be recommended on Alfisols under rainfed conditions.

A field experiment was carried out at KVK farm in Gariyaband District of Chhattisgarh State during the rabi season of 2013-14 and 2014-15 to study the efficacy of microbial inoculation with Rhizobium and Trichoderma on plant growth parameters, yield and disease resistance of 6 varieties of chickpea. Soil application with Trichoderma enriched farmyard manure in different plots was done one week before sowing and seed dressing with Rhizobium was done individually at the time of sowing. Among the chickpea varieties, JG 74 performed better in respect of nodule number., yield attributes and yield. Among the inoculants, dual application of Rhizobium + Trichoderma was found most effective in terms of improving germination, shoot length, nodule number. and also showed its positive effect in enhancement of all the yield attributing parameters (number.of pods,100 - seed weight) and yield. Study showed that inoculation with Rhizobium and soil application of Trichoderma enriched FYM gave an additive effect to seed dressing in reducing disease resistance thus enhancing crop yield.

The present study aimed to the effect of different organic manures on the growth and yield attributes of cotton by conducting field experiments during rice fallow season of 2013-14 and 2014-15 at the Tamil Nadu Rice Research Institute, Aduthurai.. The cotton growth parameters such as plant height, leaf area index, dry matter production and monopodial branches plant-1 were significantly influenced by the application of 100% recommended dose of fertilizer through vermicompost (on equal N basis). Also application of recommended dose of fertilizer through vermicompost (on equal N basis) recorded significantly higher yield attributes viz., sympodial branches plant-1, number of bolls plant-1, boll weight and seed cotton yield (17.4 and 18.6 q ha-1 during both the years, respectively). Economic analysis also indicated that Insitu vermicomposting produced higher net returns with higher B:C ratio.

A study was conducted to compare wheat production under two previous paddy crop residue management systems by taking into account wheat growth parameters, yield attributes and economics of both systems. Farm testing of wheat production in two methods of management of paddy residue viz: sowing of wheat with happy seeder in previous paddy crop residue (paddy residue retention) and sowing of wheat with normal drill after burning of previous paddy residue (paddy residue burning: farmer practice) done in Ferozepur and Jalandhar districts on 10 farmers’ fields locations in each district during rabi season of 2016-17 and 2017-18. Dataset was analyzed using unpaired T test. Both paddy residue retention and paddy residue burning methods resulted in non-significant effect on growth parameters and yield attributes which resulted similar mean grain yields (5.48 t/ha) and (5.35 t/ha), respectively in both districts during two years of study. Paddy residue retention method reduced the cost of wheat cultivation and put a check on air pollution from burning of paddy residue in the field. It saved fertilizers by adding nutrients to the field.

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.

Cowpea is a food legume very popular for its seeds and leaves in Côte d’Ivoire. This plant constitutes a significant source of financial income for vulnerable populations in rural areas. However, it production remains low in the growing areas because of the traditional practice of this food. In other words, the cultivation technique adopted for this plant is not appropriate, in particular the sowing density. To solve this problem, research work has been undertaken in 2019 and 2020 with the aim of improving the production of this crop. The first year consisted of identifying the most productive variety in a complete random arrangement with three replicates. During the second, the trials concerned the optimization of the production of this variety by controlling the seed density. For this purpose, the sowing was carried out according to three sowing densities: low density (40.000 plants/ha), middle density (134.444 plants/ha) and high density (280.000 plants/ha) in a complete random device with three repetitions. The parameters collected from sowing to harvest and after harvest were subjected to statistical analysis. Thus, it emerges from this analysis that the creeping variety recorded the best values of the growth parameters. This variety could be used as fodder for animal feed. For variables related to production, the highest values were obtained with the upright variety. The yield of this variety is doubled when cultivated at low density.  Thus, for the financial and food empowerment of cowpea producers, they will have to take an interest in the upright variety and cultivate it in low density.

The present investigation was conducted using 28 different genotypes (seven parents and their 21 F1s) of maize under organic conditions at the Rain-fed Organic Research Farm, Narayanbag, Institute of Agricultural Sciences, Bundelkhand University, Jhansi (U.P.) India, during kharif 2018 and rabi season 2018-19. In order to determine the general and specific combining ability of parents and the crosses, the growth parameters and yield components were evaluated in a 7×7 diallel fashion in maize in a Randomized Block Design (RBD) with three replications. In this study, the GCA effects suggested that parent P1, P2 and P4 were the most desirable as they possessed high GCA effect for most of the characters. Among F1 crosses, P4 x P3, P3 x P1, P5 x P3 and P7 x P5 having significant positive SCA were found to be desirable for yield and yield attributing characters. The maximum heterotic effects in desirable direction for yield attributes were showed by the cross combinations viz; P1 x P6, P2 x P7, P2 x P5, P1 x P2, P3 x P4, P5 x P7 and P3 x P5. The maximum heterosis was recorded in for Seed yield per plant P5 x P7 (39.32%) which ranged from -14.69 to 49.55.
