TPerformance of 27 improved groundnut cultivars were assessed for agronomic and physiological traits associated to improve the productivity in degraded acid soils under rainfed hilly ecosystem. The cultivars ICGS- 76 and ICGV-86590 produced significantly p less then 0.05 higher pod yield with more than 39% improvement over JL-24. The study also identified five more promising cultivars viz. ICGS-5, TKG-19 A, TG-37-A, GG-11 and GG-21 with 19-38% higher yield over the check. The low productivity of cereals in the acidic and moisture stressed Jhum degraded upland soils of rainfed hilly ecosystem of Eastern Himalayan Region is a major concern for socio-economic improvement of resource poor farmers. Adoption of these cultivars is expected to increase the productivity and net income to a tune of 93.2% without incurring any additional costs to the prevailing production system.

A field trial was conducted during two consecutive summer seasons of2012 and 2013 at ICAR-Central Potato Research Station, Shillong, Meghalaya to evaluate the integration of nutrient sources on productivity and soil health under rainfed potato cultivation in north eastern hill region of India. There were six treatments of integrated nutrient management viz., 100% Recommended dose of fertilizers,75% RDF through synthetic fertilizers and 25% recommended dose of nitrogen (RDN) through FYM, 50% RDF and 50% RDN through FYM, 25% RDF and 75% RDN through FYM, 100% RDN through FYM and control (no application of any sources of nutrients). The experiment was laid out in randomized block design with four replications. Nutrient management practices showed the significant improvement on growth and yield attributes of potato over control plot. Highest productivity of potato tubers (t/ha) was noticed with application of 75% RDF through synthetic fertilizers along with 25% RDN through FYM. Similarly, the maximum net return was associated with application of 75% RDF and 25% RDN through FYM under investigation. Application of 75% Recommended dose of nutrients through synthetic fertilizers in combination with 25% Recommended dose of nitrogen through FYM was more profitable for sustainable production of potato in the north eastern hill region of India.

Abstract Field experiments were conducted from 1991 to 1993 to evaluate eclipta, Eclipta prostrata L., control and peanut, Arachis hypogaea L., response to herbicide treatments. Fomesafen {5-[2-chloro-4-(trifluoro-methyl)phenoxy]-N-(methylsulfonyl)-2-nitrobenzamide} applied at cracking was the only preemergence-applied herbicide which provided season-long control (>84%). Herbicides applied postemergence were more effective when the eclipta was less than 5 cm in height. The most consistent early postemergence treatments were bromoxynil (3,5-dibromo-4-hydroxybenzonitrile), bentazon [3-(1-methylethyl)-(1H)-2,1,3-benzothiadiazm-4(3H)-one 2,2-dioxide], and bentazon + acifluorfen {5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrobenzoic acid} + 2,4-DB [4-(2,4-dichloro-phenoxy)butanoic acid]. Various other early postemergence followed by late postemergence sequential treatments also were equally effective. Minor peanut injury was observed at the early season rating from several herbicides; however, all injury had disappeared by the late season rating. Eclipta control did not consistently improve peanut pod yield.

SUMMARYThree short duration and one long duration groundnut genotypes, grown either ‘sole’ or as intercrops (in 1:1 ratios of the short duration with the long duration genotypes), were compared in four trials. The intercrop treatments resulted in Land Equivalent Ratios (LERs) of up to 1.25 for pod yield and total biomass despite moderate or severe water deficits at the end of the season. Specific combinations of genotypes were necessary to maximize the LER. The results indicate there is scope for achieving greater productivity in environments with a variable season length by growing late and early genotypes together in an intercrop system.

Fungicide penetration of the peanut (Arachis hypogaea) canopy to target soilborne pathogens is difficult due to the dense foliage present when mid- to late-season applications are made. To assess the effect of application timing and volume on leaf spot and stem rot control as well as peanut yield, pyraclostrobin (0.21 kg a.i./ha) or chlorothalonil (1.26 kg a.i./ha), a systemic and a contact fungicide, respectively, were applied four times on cv. Georgia Green during the day (on unfolded leaves) or at night (on folded leaves) at 187, 243, or 355 liters/ha. Night application of pyraclostrobin, across spray volumes, gave the best stem rot control and pod yield increase. Pyraclostrobin applied during the day at higher spray volumes also slightly increased control of stem rot, apparently by improving canopy penetration. Neither application timing nor spray volume affected leaf spot control with pyraclostrobin. Higher spray volumes for the chlorothalonil applications tended to improve control of early and late leaf spot, possibly by increasing coverage of foliage and stems.

A field experiment was conducted during the summer, 2014 at College of Agriculture, Vellayani, Kerala to evaluate the influence of irrigation levels, nitrogen stress and method of application of fertilizers on growth and yield of yard long bean. The experiment consisted of four levels of irrigation, two levels of nitrogen and two methods of application. The results indicated that daily irrigation at 10 mm depth and recommended dose of nitrogen (30 kg ha-1) recorded superior values for growth parameters viz., functional leaves per plant and leaf area index The major yield attributes like number of pods per plant and pod yield per plant and total pod yield were not influenced by levels of irrigation and nitrogen indicating that irrigation once in three days at 20 mm depth and nitrogen level of 22.5 kg ha-1 is sufficient for yard long bean. Soil and foliar application of nitrogen and potassium recorded superior growth characters, however, the yield was superior when the recommended dose of nutrients were supplied as soil application. Increasing irrigation interval to three days and imparting N stress did not result in any reduction in gross income and net income while, a higher benefit: cost ratio was noted in irrigation at wider intervals. Soil application of nutrients recorded higher gross income, net income and BCR compared to soil + foliar application.
