Farmers adopting higher seed rate in case of chick pea resulting in terminal moisture stress due ... more Farmers adopting higher seed rate in case of chick pea resulting in terminal moisture stress due to excess plant population and non-uniform distribution of seed. To reduce drudgery and to cover large areas in a short time, to overcome soil moisture depletion under rainfed conditions and to save seed, a ferti cum seed drill tractor drawn was developed at RARS, Nandyal, Andhra Pradesh and tested. There is a saving of 18 to 20 kg of seed per hectare when sown with the newly developed seed drill, which amounts to a saving of Rs.550 per hectare. The optimum population (34 to 37 plants per sq m) with the help of seed drill will help reduction in competition for nutrients and the available soil moisture, because of uniform distribution of seed throughout the field.
The effect of sowing time on the performance of sunflower (Helianthus annuus L.) grown under rice... more The effect of sowing time on the performance of sunflower (Helianthus annuus L.) grown under rice (Oryza sativa L.) fallow situations was studied during 1997 and 1998 in Vert/sols of northern Karnataka Early sowing resulted in better growth and recorded higher seed yield of 1,016 kg/ha and 1,010 kg/ha during 1997 and 1998 respectively. Early-planted crop gave 44.3% higher seed yield than late-planted one. Hybrids outyielded variety ‘Morden’. The hybrid ‘KBSH 1’ recorded the highest average seed yield (965 kg/ha), followed by ‘PAC 36’ (922 kg/ha). Similarly, the highest oil yield of 385 kg/ha was also obtained in ‘KBSH 1’. The productivity of all the cultivars was reduced under delayed sowing.

The experiment waslaid out in a split plot design with four main plot treatments viz., M1: Imposing moisture stress from 30-50 DAS (flowering to pegging), M2: Imposing moisture stress from 50-70 DAS (pegging to pod formation), M3 : Imposing moisture stress from 70-90 DAS (pod filling to maturity) and M4 : Moisture stress free condition and the subplots comprised of 5 varieties viz., K-6, K-9, Anantha, Dharani and Harithandhra. Moisture stress from 70-90 DAS (Pod filling to maturity) recorded highest pod yield reduction followed by stress from 50-70 DAS (pegging to pod formation) and 30-50 DAS(flowering to pegging) compared to stress free condition and thus suggesting that pod filling to maturity stage is the most critical stage. Among varieties K6, Harithandra and Anantha recorded pod yield reduction of 54.0, 53.7 and 49.3 per cent, respectively. K9 and Dharani recorded 39 and 39.7 per cent pod yield reduction. The study indicated that K9 and Dharani are drought tolerant groundnut varieties.

We have considered the variability of mandals with regard to (i) crop seasonal rainfall (mm) and (ii) pod yield of groundnut (kg/ha) during 2001 to 2020; (iii) extent of crop area (ha) during 2009 to 2020; and (iv) length of growing period (days). Based on the mean and standard deviation (SD) of each parameter, the mandals were classified into 5 groups viz., (i) G1: Less than (Mean–2SD); (ii) G2: (Mean–2SD) to (Mean–SD); (iii) G3: (Mean–SD) to (Mean+SD); (iv) G4: (Mean+SD) to (Mean+2SD); and (v) G5: More than (Mean+2SD). Out of 31 mandals, 22 mandals for area and crop seasonal rainfall, 20 mandals for LGP and 18 mandals for yield have fallen in G3. Estimates of correlation were derived between groundnut area, crop seasonal rainfall and yield f...

Performances of 12 pearl millet varieties and hybrids released for commercial cultivation in India, were estimated using RBD with three replications during rainy seasons of 2018, 2019 and 2020. The trials were conducted at the Agricultural Research Station, ANGRAU, Ananthapuramu, located in the Scarce Rainfall Zone of Andhra Pradesh, India, with an average annual rainfall of nearly 553 mm and 300 mm to 400 mm during rainy season. The environment and genotype effects were highly significant in the Additive Main Effect and Multiplicative Interaction (AMMI) model, implying that environments are varied and genotypes performed differently in each environment offering a great scope for selecting better adaptive genotypes. Apart from moisture stress, the amount of rainfall received during both the anthesis and grain maturation stages were influenced grain yield through plant height, 1000grain weight and dry fodder yield. Environment 3 was the best discriminating environment and the hybrids Pratap, 86M86 and NBH 5767 had outperformed the popular open pollinated varieties in ideal conditions. In terms of grain yield,Pusa Comp. 612 and Pratap have proved to be reliable and had a mean higher than the general mean over environments. As a result, Pusa Comp. 612 and Pratap are suggested for large-scale assessment in a wide range of locations in rainfed situations of arid regions.

Despite the fact that India has the world’s largest livestock population, feed and fodder supply is under huge strain, especially as area accessible for fodder cultivation has been shrinking. During the months of March-May and November-February are known as lean periods of fodder production, the supply of green fodder is limited throughout the year in a rainfed condition. Fodder crops develop swiftly and cover the ground surface quickly, even in low-rainfall conditions, producing a significant amount of green fodder while also providing vegetative cover over the land, resulting in resource conserving as well as increased productivity. In this context, the current study was conducted to evaluate various fodder crops, assess their productivity and quality and make appropriate recommendations for semi-arid tropics of India. Methods: Field experiments were carried ou...

The study was conducted in a 3-factor split-split plot design with conditions of (1) rainfed and irrigated as two main plots; (2) stress imposed during 30–50, 50–70, 70–90 days in 2009 and 50–90 days after sowing (DAS) in 2010 and “no stress” as four subplots; and (3) four varieties—ICGV-91114, K-6, TMV-2, and Narayani—as sub-subplots. Among varieties, Narayani gave significantly higher oil content compared with other varieties in both years. Among the stress conditions, significantly higher pod yield was attained under the no-stress condition compared with the stress that occurred during 70–90 DAS, but it was statistically at par with the stress that occurred during 30–50 and...

G. Ranga Agricultural University. Four soils (intensive, normal puddling, ordinary ploughing and soil compaction) and three water management (deep, shallow and phasic submergence) practices were tested on rabi rice in the first experiment. Three promising treatment combinations viz., intensive puddling and shallow submergence, intensive puddling and phasic submergence and normal puddling and phasic submergenee were tested on subsequent kharif rice with three weed management practices (weedy check, hand weeding and herbicide application) in the second experiment. Irrespective of water management practices, puddling was effective in reducing both weed density and dry weight all through the crop period. The results revealed that intensive puddling and shallow depth of submergence were effectiv...

The study of variance showed that the crosses had significant genetic variability. An attempt was made to choose the best hybrids for grain yield and adaptation to low rainfall regions in arid Alfisols of Andhra Pradesh. Among the tested cross combinations, ABH-61, ABH-50 and ABH-77 were found to be promising for higher yield potential, emerging as an ideal candidate for rainfed conditions. Grain weight and grain yield showed the highest GCV and PCV estimates, as well as high heritability and genetic advance as a per cent of then mean, implying that these traits were due to high additive gene effects and simple directional selection may improve them. The size of the panicle and the height of the plant had a significant and positive relationship with grain yield. As a result, selecting genotypes with longer panicles and taller plants can aid in increasing pearl millet grain yield.

Pooled data revealed that higher yield was recorded with branched varieties (447 kg ha-1) than unbranched varieties (445 kg ha-1). Unbranched variety produced higher haulm yield. Among crop geometry, 22.5 x 10 cm recorded higher seed yield of 512 kg ha-1 while lowest seed yield of 393 kg ha-1 obtained with 45x10 cm. Among crop geometry tested, higher haulm yield was registered with 45x7.5 and 22.5x7.5 cm spacing resulted lowest haulm yield. Considering the economics and large scale availability of seed drills and planters with farmers sowing of cluster bean either branched or unbranched genotypes with 30 x 7.5 or 10 cm spacing was found optimum.

Soil test-based addition of deficient micro-and macronutrients increased food grain production by 30-40% and straw (which is used as fodder) production by 10-30%. Micro-watershed scale low-cost cement-lined farm-ponds at smallholder farm level proved a scalable technology for drought-proofing of crops resulting into additional crop yield by more than 30% during 2015. Augmentation of water sources also facilitated farmers' to successfully diversify the production system. Shared machinery resources improved the operational and economic efficiency of farm sowing operations through higher crop yields by around 10%. We conclude that a mix of low-cost critical interventions if out-scaled in a large number of dryland small holdings through policy support may not only improve productivity and livelihoods, but also enhance their abilities to effectively cope with the climatic aberrations.

During 2009, higher pod and haulm yield was recorded at the distance of 9-10 m, however, it was comparable with distance of 8-9 m of tamarind trees, whereas, lower pod and haulm yield was recorded at 0-1 m distance but at par with 7-8 m distance from tamarind trees. The pod yield of groundnut was reduced to 98.9, 98.3, 96.6, 93.1, 88.6, 77.1, 54.3, 52.6 and 13.7% at 0-1, 1-2, 2-3, 3-4, 4-5, 5-6, 6-7, 7-8 and 8-9 m, respectively, compared to 9- 10 m away from tamarind trees. During 2010, higher pod yield was recorded at 9-10 m away from tamarind trees and it was significantly superior to rest of the treatments and lower pod yield was at 0-1 m away from tamarind trees. The pod yield of groundnut was reduced to 91.8, 83.7, 78.4, 64.9, 60.4, 42....
