Abstract The effectiveness of foliar fungicides for control of peanut leafspot caused by Cercospora arachidicola Hori and Cercosporidium personatum (Berk. & Curt.) Deight, was evaluated from 1971–1974. Benomyl, chlorothalonil, triphenyl-tin-hydroxide and copper hydroxide were applied at recommended rates by conventional ground sprayer at 14-day intervals. Leaf-spot severity was rated by determining percent defoliation and infection. All fungicide-treated plots had less defoliation and infection than the untreated control plots. Kernel quality was determined using Federal-State Inspection Service procedures. Plots sprayed with chlorothalonil had better quality kernels than those from any other fungicide treatment. However, kernels harvested from the untreated control plots had significantly better quality than those from the chlorothalonil-treatment. Kernels harvested from the benomyl and copper hydroxide treatments were slightly inferior in quality than the chlorothalonil treatment. Kernels from the triphenyl-tin-hydroxide treated plots were significantly inferior in quality than those from plots treated with other fungicides. These data indicate that while kernel quality is not related to leafspot control, certain foliar fungicides adversely affect peanut kernel quality probably by altering the ecology of the geocarposphere.

Rice production in Tanzania, with 67% of its territory considered semi-dry and having average annual rainfall of 300 mm, must be increased to feed an ever-growing population. Water for irrigation and low soil fertility are among the main challenges. One way to decrease water consumption in paddy fields is to change the irrigation regime for rice production, replacing continuous flooding with alternate wetting and drying. In order to assess the impact of different irrigation regimes and nitrogen fertilizer applications on growth, yield, and water productivity of rice, a greenhouse pot experiment with soil from lowland rice ecology was conducted at Sokoine University of Agriculture, Tanzania during the 2019 cropping season. The experiment was split-plot based on randomized complete block design with 12 treatments and 3 replications. Water regimes were the main factors comparing continuous flooding (CF) and alternate wetting and drying (AWD) with nitrogen fertilizer levels as the subfactor, comparing absolute control (no fertilizer) with 0 (P and K fertilizers), 60, 90, 120, and 150 kg Nha−1. Alternate wetting and drying (AWD) significantly improved water productivity by 8.3% over CF (p < 0.05). Water productivity (WP) ranged from 0.6 to 1.5 kg of rice per m3 of water. Average water use ranged from 36 to 82 L per season, and water saving was up to 34.3%. Alternate wetting and drying significantly improved yields (p < 0.05) by 13.3%, and the yield ranged from 21.8 to 118.2 g pot−1. The combination of AWD water management and 60 kg N ha−1 nitrogen fertilization application was found to be the optimal management, however there was no significant difference between 60 and 90 kg N ha−1, in which case 60 kg N ha−1 is recommended because it lowers costs and raises net income. Nitrogen levels significantly affected water productivity, water use, and number of irrigations. Nitrogen levels had significant effect (p < 0.05) on plant height, number of tillers, flag leaf area, chlorophyll content, total tillers, number of productive tillers, panicle weight, panicle length, 1000-grain weight, straw yield, grain yield, and grain harvest index. The results showed that less water can be used to produce more crops under alternative wetting and drying irrigation practices. The results are important for water-scarce areas, providing useful information to policy makers, farmers, agricultural departments, and water management boards in devising future climate-smart adaptation and mitigation strategies.

A field experiment was conducted during Rabi season of 2015-16 at the Instructional cum Research Farm, IGKV, Raipur to study the effect of different irrigation scheduling and nitrogen levels on growth, yield attributes, yield, water and nitrogen productivity of linseed (Linum usitatissimumL.). The experiment was laid out in split plot design keeping four irrigation schedules viz., come-up (I1), one (I2), two (I3) and three irrigation (I4) in main plots and four levels of nitrogen viz., control (N0), 30 kg (N1), 60 kg (N2) and 90 kg N ha-1 (N3) in sub plots with three replications. Results revealed that highest seed yield was obtained with linseed provided two irrigations (1683 kg ha-1) and application of 90 kg N ha-1 (1604 kg ha-1). Moreover, crop supplied with two irrigations in combination with 90 kg N ha-1 (I3×N3) gave significantly (P=0.05) highest seed yield (2097 kg ha-1) compared to rest of the treatment combinations. The excessive use of irrigation and fertilizers also affects farmer’s economy, as the crop is relatively low yielder. Two irrigations are better than three irrigations in terms of seed yield and water productivity; and application of 60 kg N is better than 90 kg N ha-1 in view of nitrogen productivity. The WP and IWP were decreasing as increasing the number of irrigation, but increasing with increasing the levels of nitrogen, while NP was highest with two irrigations (11.09 kg, kg-1 N) and application of 60 kg N ha-1 (8.90 kg, kg-1 N).

A field experiment was conducted at research farm, Agricultural Research Sub-Station, Hanumangarh, Swami Keshwanand Rajasthan Agricultural University, Bikaner, Rajasthan during Kharif, 2016 to study the effect of water and nitrogen levels on yield attributes, water productivity and economics of cluster bean [Cyamopsis tetragonoloba (L.) Taub.].Cluster bean variety RGC-1055 with seed rate of 16 kg/ha was planted using 3 levels of irrigation (100, 200 and 300 mm) and 4 level of nitrogen (0, 20, 40 and 60 kg/ha) and analyzed in split plot design with three replication. Results showed that irrigation at 200 mm significantly increased number of pods/plant (44.7), number of seeds/pod (7.8), test weight (28.7g), net returns (Rs 31179/ha) and B:C ratio (2.1) over 100 mm irrigation level.However, water productivity (0.25 kg m-3) was highest at 100 mm irrigation level. Nitrogen level at 40 kg/ha significantly increased number of pods/plant (48.3), number of seeds/pod (8.4), test weight (32.2 g), net returns (Rs.32273/ha), B:C ratio (2.12) and water productivity (0.27 kg m-3) over no application of N.
