Abstract
A field experiment was conducted during rainy (kharij) season of 2004 and 2005 at crop research farm of the University, Hisar, to find out suitable spacing for pearl millet (Pennisetum glaucum L.) hybrids along with N and P levels so as to increase the productivity of pearl millet. The experiment was laid out in split-plot design allocating 2 hybrids and 3 plant densities in main plots and 4 fertility levels in sub-plots replicated thrice. Highest grain yield (3.53 tonnes/ha) was recorded when the crop was sown at plant density of 45 cm x 12 cm and fertilized with 90 kg N + 45 kg P 2 O 5 /ha but was at par with 60 kg N + 30 kg P 2 O 5 /ha. 'HHB 67-2' pearlmillet hybrid recorded relatively higher value for consumptive use of water, water-use efficiency and grain yield.

Abstract Serious water deficits are threatening agricultural sustainability in many regions of the South Asia (SA). While the increase in crop production of irrigated rice–wheat system in SA has been impressive since the 1970s, the low water productivity (WP) has led to the depletion of surface water and groundwaters. In this chapter we have discussed the availability of water resources in SA, identified the positive effects of soil and water management and crop genetic improvement on WP, and th...

A field experiment was conducted in 2010/11 and 2011/12 at New Delhi to study the performance of zero-till rainfed mustard. The influence of preceding rainy season crops, viz. pearl millet, cluster bean and green gram; and residue management, viz. no residue, crop residue and Leucaena twigs mulching on this mustard crop was observed. Pooled analysis of mustard seed yield was significantly higher (+51%) in 2010/11 (1.80 t/ ha) than 2011/12 (1.19 t/ha) due to favourable weather condition in the fi...

Under limited moisture conditions integrated nutrient management and conservation agriculture (CA) practices plays a vital role. Information on effect of integrated nutrient management (INM) with CA practices in pearlmillet (Pennisetum glaucum)-mustard (Brassica juncea) system is lacking. The present experiment was conducted during 2005-06 and 2006-07 in rainy and winter seasons, at IARI, New Delhi, India to investigate the effect of INM and tillage on pearlmillet-mustard system under limited ir...

Yields of field crops in Indo-Gangetic plains of India have decreased due to the advent of increasing water scarcity in this century. The water is a very limiting input in this region for the crop production; its efficiency is quite low in the range 30–40 per cent, thereby about 60–70 per cent of irrigation water is lost during conveyance and application. Irrigation farming, the greatest water user of all, has been made responsible for inefficient water use. There is also not available new land ...

Field experiments were conducted at Agricultural Research Station, Mannuthy during 2004 and 2005 to fine tune the technology of dual culturing of rice (Oryza sativa) and green manure crops to ensure the supply of required quantity of organic manure to dry seeded rice in a cost effective manner. Two green manure crops viz., horse gram (Macrotyloma uniflorum (Lam) Verdc) and cowpea [Vigna unguiculata (L.) Walp.] sown along with rice were incorporated at 45 days after sowing by three methods viz., ...
