A field experiment was conducted at the Maize Research Centre, Agricultural Research Institute (ARI), Rajendranagar, Hyderabad during the rabid seasons (15 October to 15 January) for two years to study the effect of plant densities and nitrogen levels on growth parameters, yield characteristics, yield and economics of the newly published popcorn hybrid BPCH-6 by Professor Jayashankar Telangana State Agri-6 (Previously Acharya NG Ranga Agricultural University). Three plant densities (P1–1,11,111 ha-1 (60 x 15 cm), P2–1,11,111 ha-1 (45 x 20 cm) and P3–83,333 ha-1 (60 x 20 cm) and four levels of nitrogen (N1–80 kg ha-1, N2–120 kg ha-1, N3–160 kg ha-1 and N4–200 kg ha-1) were taken in a randomised block configuration with three repeated factorial principles.  Significantly higher plant height with a population of 1, 11,111 ha-1 (45x20 cm), significantly higher leaf area index with a population of 1, 11,111 ha-1 (60x15 cm) and significantly higher dry matter production (g plant-1) with a population of 83,333 plants ha-1 (60x20 cm) was observed as per pooled mean over two years.  Yield attributes like cob girth, number of rows cob-1 and 100 seed weight were not influenced significantly whereas cob length and number of seeds row-1 were significantly superior with optimum plant density of 83,333ha-1. A plant density of 1, 11,111 ha-1 (60x15 cm).  recorded significantly higher cob, grain fodder yields. When a population of 1, 11,111 plants ha-1 (60x15 cm) was maintained, gross and net returns and profit cost ratios were higher. The use of 200 kg of nitrogen ha-1 resulted in slightly higher growth parameters, yield characteristics and yield, but it was equal to 160 kg of N ha-1  and both were greater than 120 and 80 kg of N ha-1.. Application of 160 Kg N ha-1 recorded higher gross and net returns and benefit cost ratio compared to 200 Kg N ha-1.

An experiment was conducted with the objective of ascertaining the feasibility of cultivation of pigeonpea during rabi season in the alfisols of Southern Telangana Zone. Further, it was designed to understand the performance of pigeonpea genotypes at various plant densities and also the economics of pigeonpea cultivation during rabi season. It consisted of 12 treatments with four plant densities in main plots and three genotypes in sub plots in split plot design. The pooled data of 2015-16 and 2016-17 revealed that significantly higher seed yield (1532 kg ha-1) was recorded at plant density of 60 cm × 10 cm spacing than at 45cm × 10cm (1332 kg/ha), 75 cm × 10 cm (1321 kg/ha) and 90 cm × 10 cm (1141 kg/ha). Among the genotypes, the seed yield in PRG-158 (1547 kg/ha) and Asha (ICPL 87119) (1591 kg/ha) was on par with each other but significantly higher than in PRG-176 (857 kg/ha). The higher gross returns (Rs. 77366 ha-1), net returns (Rs.46733 ha-1) and benefit cost ratio (2.53) was recorded at plant density of 60 cm × 10 cm spacing than at other tested plant densities (45 cm × 10 cm, 75 cm × 10 cm and 90 cm × 10 cm). Among the genotypes, Asha (ICPL 87119) registered highest gross returns (Rs. 80346 ha-1), net returns (Rs.49711 ha-1) and benefit cost ratio (2.62) followed by PRG-158 (gross returns of Rs. 78124ha-1, net returns of Rs.47489 ha-1 and benefit cost ratio of 2.55) and PRG-176 (gross returns of Rs. 43279ha-1, net returns of Rs.13144 ha-1 and benefit cost ratio of 1.44). Thus, the spacing of 60 cm × 10 cm is recommended for the cultivation of pigeonpea during rabi season in alfisols of Southern Telangana Zone with long duration varieties like PRG-158 and Asha (ICPL-87119).

A field experiment was carried out to study the “Effects of different maize–soybean intercropping patterns on yield attributes, yield and B: C ratio” at the Agricultural Research Farm, Bhagwant University, Ajmer. Treatment consists of Sole maize (60x20 cm), Sole Soyabean (30x10 cm), Maize-Soybean (1:1) (60X20 cm), Maize-Soybean (1:1) (75X20 cm), Maize-Soybean (1:1) (90X20 cm), Maize-Soybean (1:2) (90X20 cm) and Maize-Soybean (2:6) (Paired row 45/180 cm). There were four replicated blocks and plot sizes measuring 7 m x 4.5 m laid out in a randomized complete block design (RCBD). Results of the experiment showed that the maize-soybean intercropping patterns had significant effect on maize stover and grain yields. Sole maize recorded significantly higher yield than intercropped maize under varying geometry and row proportion. However, it was at par with maize intercropped with soybean in 1:1 row proportion with 60 x 20 cm .The intercropping patterns affected significantly the PAR intercepted and the leaf area index. The soybean sole crop intercepted significantly more light and leaf area index (LAI) than all other treatments and/or crop. Further,, the yield of sole soybean was significantly superior over other intercropped treatments. The highest benefit cost ratio revealed that higher return per unit money invested for inputs used for raising crops. The highest B: C ratio was recorded with maize + soybean in 2:6 paired row (3.57) intercropping system. The least B: C ratio was recorded in sole soybean (2.45).

A field experiment was conducted during 2006-07 and 2007-08 at Precision Farming Development Centre, Indira Gandhi Agricultural University, Raipur, Chhattisgarh, India, to evaluate the production, potential and economics of capsicum (Capsicum annum L.) as influenced by drip irrigation and mulches. Experiment was laid out in a split-plot design replicated thrice with irrigation levels 1.0 Epan (Pan evaporation) through drip, 0.8 Epan through drip, 0.6 Epan through drip and 1.0 Epan with flood irrigation (FI) in main plot and mulches (i.e. no mulch (Glyphosate @ 6.0 ml l-1 followed by 2 hand weedings), black polythene mulch (BPM: 40 ? thickness), transparent polythene mulch (TPM: 40 ? thickness), paddy straw mulch (PSM: 5 t ha-1) in sub plots. The growth parameters like plant height, number of primary and secondary branches, stem girth, leaf area, leaf area index, dry weight of leaf, stem, fruit and total dry weight were maximum with drip irrigation at 1.0 Epan followed by drip irrigation at 0.8 Epan. Among the mulches the maximum values of the growth parameters were noticed with black polythene mulch followed by paddy straw mulch. The yield attributes like fruit length, fruit volume, fruit girth, per cent fruit set, fruits/plant, green capsicum fruit weight and yields were higher with drip irrigation at 1.0 Epan followed by drip at 0.8 Epan. Among the mulches, all the yield attributes were found higher with black polythene mulch followed by paddy straw mulch; whereas least yield attributes were measured with no mulch. Marginal cost, marginal return, MR: MC, cost of cultivation, net returns and B: C were higher with drip irrigation at 1.0 Epan followed by drip irrigation at 0.8 Epan. Among different mulches all the economic parameters were higher with black polythene mulch followed by paddy straw mulch except MR: MC and B: C ratio. Capsicum with paddy straw mulch produced higher values of MR: MC and B: C ratios. DOI: http://dx.doi.org/10.3329/sja.v10i2.18323SAARC J. Agri., 10(2): 51-60 (2012)

The research was conducted at Beltari Sandhikharka-10, Arghakhanchi district to study about the effect of various doses of boron on growth and yield attributing characters of cauliflower (Brassica oleracea var. botrytis) during off-season from February to June in 2020. Five treatments; B0 (control/no application), B1: 2kg/ha, B2: 4kg/ha, B3: 6kg/ha, B4: 8kg/ha which are the different doses of boron application were laid out in Randomized Complete Block Design (RCBD) with 4 replications. The growth parameters like plant height, number of leaves per plant leaf length and leaf breadth of largest leaf were recorded multiple times with 15 days interval. Days to curd initiation and Days from curd initiation to harvest were recorded by regular field observation. The yield parameters; curd weight with leaves, Marketable curd weight, average curd yield, incidence of hollowing were recorded during harvest. The economics from application of boron doses in cauliflower production was obtained in terms of cost of cultivation, gross returns, net returns, and benefit cost ratio. The result showed that the growth and yield attributing characters of cauliflower were significantly affected by application of boron in which the value of these parameters was found significantly higher in B1 followed by other treatments. The average curd yield of cauliflower in B1 was found to be 12.39 mt/ha which was 48.92% higher than that of B0 with curd yield 8.32 mt/ha. Similarly, the net return was found significantly the highest in B1 and the lowest in B0. The result showed that application of boron in the range of 2-4 kg/ha is preferred to control and higher doses in respect of both productivity and economics.

Abstract Crop models can be used to explain yield variations associated with management practices, environment and genotype. This study aimed to assess the effect of plant densities using CSM-CROPGRO-Soybean for low latitudes. The crop model was calibrated and evaluated using data from field experiments, including plant densities (10, 20, 30 and 40 plants per m2), maturity groups (MG 7.7 and 8.8) and sowing dates (calibration: 06 Jan., 19 Jan., 16 Feb. 2018; and evaluation: 19 Jan. 2019). The model simulated phenology with a bias lower than 2 days for calibration and 7 days for evaluation. Relative root mean square error for the maximum leaf area index varied from 12.2 to 31.3%; while that for grain yield varied between 3 and 32%. The calibrated model was used to simulate different management scenarios across six sites located in the low latitude, considering 33 growing seasons. Simulations showed a higher yield for 40 pl per m2, as expected, but with greater yield gain increments occurring at low plant density going from 10 to 20 pl per m2. In Santarém, Brazil, MG 8.8 sown on 21 Feb. had a median yield of 2658, 3197, 3442 and 3583 kg/ha, respectively, for 10, 20, 30 and 40 pl per m2, resulting in a relative increase of 20, 8 and 4% for each additional 10 pl per m2. Overall, the crop model had adequate performance, indicating a minimum recommended plant density of 20 pl per m2, while sowing dates and maturity groups showed different yield level and pattern across sites in function of the local climate.

AbstractHigh density planting system i.e. accommodating a higher number of plants than routine in a given area is an innovative agro-technology to increase yield and thereby early net returns. Due to conventional wide spacing plantation in Nagpur mandarin (Citrus reticulata Blanco), the land remains unutilized as the plant canopy gradually increases over the years. In the present study, Nagpur mandarin (Citrus reticulata Blanco) budded on Rangpur lime rootstock was evaluated under six different planting spacings. It was observed that the organic carbon (1.10–1.82%) and major nutrients viz. N (309–430 kg ha−1), P (20–54 kg ha−1) and K (291–810 kg ha−1) increased vis-à-vis plant density and was highest under 2 × 2 m spacing. Plants were tallest at 2 × 2 m spacing with the higher PAR interception (88.2) and the lowest leaf area index (1.09). Fruit yield on area basis, under 2 × 2 m spacing was 26, 7.1, 4.6 times more as compared to conventional plantation during the first, second and third year, respectively. At fifth year of crop harvest, the highest B:C ratio (6.36) was recorded in 6 × 3 m followed by 4 × 2 m and 2 × 2 m.
