Background: Irrigation and proper nutrient management that determines the productivity of the groundnut especially during the critical stages of the crop growth. Methods: The experiments laid out in split plot design comprising of three levels of irrigation scheduling [0.8 IW/CPE ratio (I1), 0.6 IW/CPE ratio (I2) and 0.4 IW/CPE ratio (I3)] in main plots and four nutrient management practices viz., N1- 75% of RDF with 5 t of charred rice husk, N2 - 50% of RDF with 5 t of charred rice husk, N3 - 75% of RDF with 5 t of charred rice husk along with seed treatment of Abuscular mycorrhiza and N4 - 50% of RDF with 5 t of charred rice husk along with seed treatment Arbuscular mycorrhiza in sub plots and replicated thrice. Result: Highest pod yield (2003, 2099 and 2063 kg ha-1 during summer, kharif and rabi 2017, respectively) of groundnut was registered with irrigation scheduling at 0.8 IW/CPE ratio along with 75% of RDF and 5 t of charred rice husk as basal with seed treatment of Arbuscular mycorrhiza. The maximum water use efficiency was also recorded under of the same treatment (4.16, 7.07 and 4.86 kg ha-1 mm-1 during the various seasons respectively). The highest B:C ratio of 2.2, 2.4 and 2.2 was recorded during summer, kharif and rabi 2017, respectively were also registered with same combination irrigation and nutrient management.

Background: Different levels of nutrient management practice and soil amendments charred rice husk with Arbuscular mycorrhizae during the critical stages of the crop growth enhances the productivity of the groundnut crop. Methods: The field experiments were conducted summer, kharif and rabi seasons of 2016-17 and 2017-2018 at AC and RI, TNAU, Madurai. The main plots consisted of three levels of irrigation scheduling viz., I1- 0.8 IW/CPE, I2- 0.6 IW/CPE and I3- 0.6 IW/CPE ratio and sub plot comprised of four level of nutrient management practices viz., N1-75% of recommended dose of fertilizer with 5t of charred rice husk, N2- 50% of recommended dose of fertilizer with 5t of charred rice husk, N3-75% of recommended dose of fertilizer with 5t of charred rice husk along with seed treatment of Arbuscular mycorrhiza and N4- 50% of recommended dose of fertilizer with 5t of charred rice husk along with seed treatment Arbuscular mycorrhiza. Result: The study revealed that the highest plant height, dry matter production, leaf area index, leaf single photon avalanche diode value, pod yield and haulm yield, nutrient uptake (N,P,K) of groundnut crop and soil enzyme activities in soil was registered with the application of 75% recommended dose of fertilizer and 5t of charred rice husk as basal with seed treatment of Arbuscular mycorrhiza. The highest pod and haulm yield of 1783, 1935 and 1854 kg ha-1 and 4743, 4272 and 4338 kg ha-1 during summer, kharif and rabi’ 2017 seasons respectively of groundnut was registered with 75% of recommended dose of fertilizer and 5t of charred rice husk as basal with seed treatment of Arbuscular mycorrhiza.

ABSTRACT The aim was to determine the efficiency of use of water and nitrogen for forage production and goat-milk production on an irrigated Tanzania Guineagrass (Panicum maximum cv. Tanzânia) pasture subjected to different management practices. The management levels tested were combinations among nitrogen fertilization levels and post-grazing residual heights (ResH): Intensive (ResH = 33.0cm and 600.0kg N/ha.year-1); Moderate (ResH = 47.0cm and 300.0kg N/ha.year-1); Light (ResH = 47cm and 0kg N/ha.year-1); and Conventional (ResH = 33cm and 0kg N/ha year-1). The efficiency of water use for forage production was higher in intensive and Moderate management. The Conventional management was recommended only for forage production since there is no nitrogen input available because this result was similar to Intensive management in water efficiency. The efficiency of water use to produce goat milk was higher in Intensive management. Moderate management presented higher efficiency of nitrogen to produce forage. On the other hand, Intensive management was more efficient using nitrogen in goat milk production. The amount of water needed to produce one liter of goat milk varied from 893.20 to 3,933.50L. In the moderate management, up to 121.48kg forage and 21.56kg of milk were produced for every kilogram of N utilized. Intensive management is advantageous for water use efficiency as well nitrogen efficiency to produce goat milk in cultivated pasture.
