Abstract

Six on-farm demonstrations were conducted to popularize the effect of irrigation on growth, yield components, yield and economics of chickpea in two villages viz., Akuledu and R. Kothuru of Anantapuram district with an area of 7.2 hectares during Rabi season over a period of 3 years from 2007-08 to 2009-10. The results revealed that growth parameters like plant height, number of pods per plant, hundred pod weight, hundred seed weight of chickpea were improved by providing irrigation at 35 and 55 DAS compared to farmers practice. By giving irrigation at 35 and 55 DAS plant height, number of pods per plant, 100 pod weight and 100 seed weight were increased by 9.1, 38.7, 16.9, and 23.4 per cent, respectively over farmers practice. Irrigation at 35 and 55 DAS recorded higher seed yield (2006 kg ha^-1) which was 35.1 per cent higher over farmers practice (1485 kg ha^-1). Gross returns (Rs. 44655/-) and net returns (Rs. 34080/-) per hectare were more with irrigation at 35 and 55 DAS compared to farmers practice (Rs. 32783/- gross returns and Rs. 19908/- net returns).

Abstract

To popularize herbicides usage in groundnut cultivation 15 on-farm demonstrations were conducted in farmers fields with an area of 12.0 hectares under supervision of DAATT Centre (Extension unit of Acharya N.G. Ranga Agricultural University, Andhra Pradesh), Anantapuram during Rabi season over a period of 3 years from 2011-12, 2012-13 and 2013-14. The treatments consisted of T₁: Herbicide application (Pendimethalin @ 3.75 lit/ha as pre-emergence + quizalopop ethyl @ 1.0 lit/ha as post-emergence at 20 days after sowing + one hand weeding at 40 days after sowing) T₂: farmers practice (Manual weeding with Danthulu twice at 20 and 40 days after sowing) with an objective to obtain higher productivity, to reduce the cost of cultivation of groundnut and subsequently improve the returns from unit area in farmers' fields. Demonstrations revealed that application of pendimethalin @ 3.75 lit/ha immediately after sowing + quizalopop ethyl @ 1.0 lit/ha at 20 days after sowing + manual weeding at 40 days after sowing has recorded higher pod yield (2252 kg ha^-1) which was 15.2 per cent higher over farmers practice (1955 kg ha^-1). A saving of Rs. 4000/- (Rupees four thousand only) on cost of cultivation per hectare was realized with herbicide application besides increasing groundnut yield. Higher gross returns (Rs. 1,05,844/-) and net returns (Rs. 83,094/-) per hectare were with herbicide application compared to farmers practice (Rs. 91,885/- gross returns and Rs. 65,135/- net returns). Due to herbicide application cost of cultivation was reduced by 15.3 per cent whereas, gross returns and net returns were improved by 20.1 and 43.1 per cent, respectively over farmers practice.

Abstract

On farm demonstrations were conducted in farmers fields to popularize zero tillage maize technology among farmers under supervision of DAATT Centre (Extension unit of Acharya N.G. Ranga Agricultural University, Andhra Pradesh), Anantapuram for four years during Rabi, 2011-12, 2012-13, 2013-14 and 2014-15. The comparison was made between zero tillage maize and farmers practice (traditional maize cultivation) with an objective to obtain higher maize productivity and net returns in farmers fields under zero tilled conditions. Results revealed that higher cob length of 17.4 cm was recorded with zero tillage maize compared to farmers practice (15.5 cm). Higher grain weight per plant of 129 g was recorded with zero tillage maize compared to farmers practice (115 g). There were more number of grains per cob (421) in zero tillage maize as compared to 385 grains per cob in farmers practice. Higher 100 grain weight of 26.2 g was recorded with zero tillage maize compared to farmers practice (23.6 g). In zero tillage maize cob length, grain weight / plant, number of grains/cob and 100 grain weight were increased by 12.3, 12.2, 9.4 and 11.0 per cent, respectively over farmers practice. Zero tillage maize recorded higher grain yield (6250 kg ha-1) and stover yield (7750 kg ha-1) which was 11.4 and 6.9 per cent, respectively higher over farmers practice (5610 kg ha-1grain yield and 7250 kg ha-1 stover yield). Gross returns (Rs. 93,750/-) and net returns (Rs. 78,000/-) per hectare were more with zero tillage maize compared to farmers practice (Rs. 84,150/- gross returns and Rs. 62,500/-net returns). Simultaneously cost benefit ratio was higher with zero tillage maize (1:5.9) compared to farmers practice (1:3.9) because of lower cost of cultivation and improved yield with zero tillage maize. In zero tillage maize cost of cultivation was reduced by 27.3 per cent whereas, gross returns and net returns were improved by 11.4 and 24.8 per cent, respectively over farmers practice.

Abstract

Field experiments were conducted in the wetland farm of S.V. Agricultural College, Tripati (Acharya N.G. Ranga Agricultural University), Andhra Pradesh for two consecutive years 2002 - 2003 and 2003 - 2004 and results revealed that regardless of the preceding crops tried for incorporation of crop residues prior to rice. Nitrogen management practice of substituting 100 per cent of recommended dose of nitrogen through FYM to rice has resulted in build up of soil fertility status in terms of organic carbon. availahle N, P and K after entire cropping system. By raising a reasonably short duration leguminous crop (either a pulse crop or vegetable crop depending up on the farming situation) preceding to rice and incorporation of the crop residues after picking the economic yield and supply of 50 per cent recommended dose of nitrogen each through fertil izer and FYM to rice followed by raising groundnut as residual crop, to utilize the residual fertility was found the best nitrogen management package for rice-groundnut cropping system, not only in terms of higher productivity and economic returns, but also for sustaining the soil fertility status at a fairly high level.
