ABSTRACT
A field experiment was conducted during kharif 2022 at College of Agriculture, Kalaburagi to evaluate the effect of dates of sowing and plant geometry on yield and economics of ricebean. The experiment was laid out in Split plot design with three replications. The experiment was comprised of two factors viz., dates of sowing in main plot with four dates i.e. second fortnight of July, first fortnight of August, second fortnight of August and first fortnight of September and spacing in sub plot with three plant geometry i.e. 30 cm x 10 cm, 45 cm x 10 cm and 60 cm x 10 cm. The results of the experiment indicated that ricebean sown during first fortnight of August recorded significantly higher seed yield and stover yield (1016 kg ha-1 and 2574 kg ha-1, respectively) besides higher gross returns (?. 63547 ha-1), net returns (?. 39300 ha-1) and Benefit Cost ratio (2.62). Among different plant geometry, 30 cm x 10 cm recorded significantly higher seed and stover yield (1009 kg ha-1 and 2302 kg ha-1, respectively) besides higher gross returns (?. 62852 ha-1), net returns (? 38205 ha-1) and BC ratio (2.55). Further, it was onpar with 45 cm x 10 cm plant geometry (989 kg ha-1, 2253 kg ha-1, ?. 61583 ha-1, ?. 37355 ha-1 & 2.54, seed yield, stover yield, gross returns, net returns & BC ratio, respectively). The interaction between dates of sowing and plant geometry on yield attributes, yield and economics was found non significant.
ABSTRACT
Aims: To identify the optimum sowing time and suitable varieties of soybean for profitable cultivation during the off-season in the Northern Telangana Agroclimatic zone of Telangana state in India.Study Design: Strip plot design with three replications.Place and Duration of Study: The Regional Sugarcane and Rice Research Station, Professor Jayashankar Telangana State Agricultural University (PJTSAU), Rudrur, Nizamabad District, Telangana state, India, between October 2022 and June 2023.Methodology: The field experiment was conducted in medium clay loam soil under irrigated condition. The experiment was laid out in strip plot design with three varieties viz., JS 335 (V1), ASB 22 (V2) and KDS 726 (V3) as horizontal strips and nine dates of sowings viz., 3 Oct (D1), 19 Oct (D2), 3 Nov (D3), 19 Nov (D4), 3 Dec (D5) 19 Dec (D6), 3 Jan (D7), 19 Jan (D8) and 3 Feb (D9) as vertical strips, replicated thrice. The seeds were sown by dibbling at 5 cm apart within the row and rows were space at 45 cm apart. Standard recommended package of practice of kharif season suggested by PJTSAU was followed. The data on growth yield attributes was recorded on selected 5 plant, averaged/ plant and grain yield was recorded from net plot, converted to one hectare and analyzed statistically using OP Stat.Results: The results of the experiment revealed that, the cv. KDS 726 recorded the maximum plant height (35.2 cm) and biomass accumulation (8.93 g plant-1) which was significantly more over the cv. JS 335 and cv. ASB 22 in 3 Nov and 19 Oct sowings, respectively. The cultivars the cv. JS 335 (V1) recorded more number of pods over cv. ASB 22 (V2) and cv. KDS 726 (V3) in 19 Oct (D2), 3 Nov (D3), 19 Nov (D4), 3 Dec (D5) and 3 Jan (D7) sowings. The cv. KDS 726 (V3) was found superior in terms of seeds pod -1 (3.0) which was comparable to cv. JS 335 (V1) and significantly more over cv. ASB 22 (V2) when it was sown on 19 Oct (D2). The cv. KDS 726 (V3) recorded significantly more test weight (g) over cv. JS 335 (V1) and cv. ASB 22 (V2) from 19 Oct (D2) to 3 Jan (D7) sowings. The cv. ASB 22 sown on 3 Oct produced significantly more seed yield (753 kg ha-1) and haulm yield (1599 kg ha-1) over cv. JS 335 and cv. (KDS 726). Conclusion: The soybean cv. ASB 22 with sowing first week of Oct was found to be suitable for cultivation during the off season.
ABSTRACT
The field experiment was titled “Effect of dates of sowing on growth and yield of Chickpea varieties” was conducted during rabi 2022-23, at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (UP). The soil of the experimental plot was sandy loam in texture. The experiment consists of three varieties (Himmat, Shulabh-45 and Chirag) and three different dates of sowing November 5th, November 15th and November 25th including control i.e., blanket application of 20-60-20 kg/ha of NPK (farmer's practice) which were replicated thrice. The experiment was laid out in Randomized Block Design with ten treatments viz., T1: Himmat + November 5, T2: Himmat + November 15, T3: Himmat + November 25, T4: Shulabh-45 + November 5, T5: Shulabh-45 + November 15, T6: Shulabh-45 + November 25, T7: Chirag + November 5, T8: Chirag + November 15, T9: Chirag + November 25, and control plot. The results of the experiment concluded that the variety Shulabh-45 with the date of sowing on November 25th significantly increased the growth parameters viz., plant height (45.54 cm), Number of nodules per plant (31.87), Plant dry weight (20.45 g/plant), and yield parameters viz., pods per plant (35.53), seeds per pod (1.35), seed yield (3.37 t/ha) and stover yield (4.90 t/ha). This treatment also showed its positive effect on economics viz., gross returns (1,71,870 INR/ha), net returns (1,19,475 INR/ha), B:C (2.28).
ABSTRACT
The present study aimed to investigate the influence of Dates of sowing and Spacing on Growth and Yield of Sorghum (Sorghum bicolor L.). A field experiment was carried out during Zaid season of 2022 at the Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P.) India. The treatments consist of Dates of sowing 1stfortnight June,2ndfortnight June,1stfortnight July and Spacing of S1- 20×15cm, S2- 40×15cm, S3- 60×15cm. There were 10 treatments each replicated thrice. The soil of experimental plot was sandy loamy in texture, nearly neutral in soil reaction (pH 7.8), low in organic carbon (0.35%) available N (163.42 kg/ha), available P (21.96 kg/ha) and available K (256.48 kg/ha). Results revealed that the higher plant height (207.41cm), higher plant dry weight (94.86 g/plant), higher number of Grains/ear head (1588.30), higher Test weight (14.93 gm), and higher Grain yield (5.57 t/ha) yield were significantly influenced with sowing time of 2ndfortnight June along with the spacing 40×15cm.
ABSTRACT
A field experiment to study the impact of sowing dates on Rice leaf folder in direct seeded rice was conducted at Agricultural College Farm, Bapatla during kharif, 2021. Early planted rice crop had lower pest than later transplanted rice. Various dates have a significant impact on the occurrence of biotic stress, particularly insect pests. To identify suitable plating dates to minimize the leaf folder infestation in paddy the following experiment was conducted. Sowing was done at four different dates with 10 days interval which were taken as treatments each replicated with five times and the data has also been correlated with light trap data. The mean per cent damage ranged from 9.44 to 16.64 %. Highest infestation (16.64 %) was observed in last date of sowing and least damage (9.44 %) was observed in first date of sowing. Correlation analysis of light trap catch data shown a positive correlation with morning (r = 0.373) and evening (r = 0.186) relative humidity while a negative correlation with maximum (r = - 0.182), and minimum (r = - 0.017) temperatures and rainfall (r= - 0.154). Multiple Linear Regression (MLR) of trapped adult number and climatic conditions at different sowing dates revealed that weather parameters contributed to the variation in moth number trapped in light trap by 35.4 per cent in first date of sowing, 42.2 per cent in second date of sowing, 59.6 per cent in third date of sowing, and 50.7 per cent in fourth date of sowing. Yield ranged from 3632 kg ha-1 in last date of sowing to 5156 kg ha-1 in first date of sowing.
