A field experiment was conducted with an objective to improve potato production through non monetary agronomic manoeuvring during the Zaid season of 2015-2016 and 2016-2017 at three village’s viz. Audung, Seru and Namtsering in Tawang district of Arunachal Pradesh. Experiment consist of four inter row spacing and five earthing up treatments. Results revealed that growth, development, yield attributes and tuber yield was greatly influenced by the treatment under investigation. Majority of growth and yield parameters was recorded maximum with the row spacing of 40 and 30 cm inter row spacing. Significantly the highest marketable tuber yield (15.3 t/ha) was produce at 30 cm inter row spacing. Earthing up at 15 days after plant emergence resulted superior performance in most growth and yield parameters. For better potato production 30 cm intr row spacing and earthing up at 15 days after emergence can be used advocated for Tawang district (Arunachal Pradesh).

Potato (Solanum tuberosum L) is a strategic national food security crop in that can be used as a supplement for carbohydrates. It is the fastest growing staple food crop and source of income for poor smallholder farmers. There is limited documentation on effects of earthing up irish potatoes on yield and yield components in Zimbabwe. A field experiment was conducted in Zaka district of Masvingo province in Zimbabwe during the 2018/19 cropping season. The aim of the study was to investigate the effect of time of earthing up on yield and yield parameters of BP1 potato variety. The treatments consisted of four levels of time of earthing up (no earthing up (control), three, four and five weeks after plant emergence), replicated three times on a Randomized Complete Block Design (RCBD). Results on earthing-up at three weeks recorded significantly (P<0.013) the highest total tuber yield (21.97 t ha-1) which is 10% higher compared to no earthing up which recorded 14.43 t ha-1. Moreover, earthing up at two weeks had the least number of greening tuber yield (3%), 11% pest damaged tuber yield, 6% unmarketable tuber yield and 45% marketable tuber yield. This is in contrast with no earthing up which recorded 91% greening tuber yield, 25.3% on pest damaged tubers, 59% on unmarketable tubers and 10% marketable tuber yield. Based on the results, first earthing up should be done at three weeks after complete plant emergence at the study area under rain fed conditions for the production of potatoes with improved yield and better tuber quality.

The present study entitled “Bioefficacy study of Bacillus subtilis based biofungicide on leaf spot disease, growth and yield attributes of tomato [Solanum lycopersicum L.] cv. ArkaVikas” was conducted at Vegetable Research Farm, Department of Horticulture, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi during rainy season of 2016-17 in Randomized Block Design (RBD) with three replications. The treatments included foliar spray of chemical fungicide (Copper oxychlooride) and biofungicide (Taegro® and Trichoderma) either alone or in combination. Taegro® is a bacterial biofungicide containing 1×1010 CFU/g (13%w/w) of Bacillus amyloliuefaciens strain FZB24 formulated as WP. A total of 12 characters including disease, growth and yield parameters were studied. Disease parameter included leaf spot disease incidence (%) and disease severity (%) whereas growth and yield parameters included days to 50% flowering, height, number of branches per plant, fruit length (cm), fruit width (cm), number of fruits per plant, average fruit weight (g), number of seed per fruit, fruit yield per plot (kg), fruit yield per hectare (kg) were studied. The biofungicide Taegro exhibited significant potential in reducing the leaf spot in tomato and improving the growth and yield attributes of tomato as compared to control. But combined used of Taegro with standard chemical copper oxychloride gave better result than Taegro alone. As a consequence, this may be used as part of an integrated disease management approach so as to minimizes the use of standard fungicides and also protect the environment from pollution and maintenance of the human health.

A field experiment was carried out during the rabi seasons of 2016-17 and 2017-18 at Agronomy Farm, S.K.N. Agriculture University, Jobner, Jaipur, Rajasthan, to evaluate the effect of sowing at different thermal regimes and foliar sprays of bio-regulators on growth and yield of wheat. The treatments comprised three sowings (22ºC, 20ºC and 18ºC) and eight bio-regulators (control, water spray, SA @ 100 ppm, SA @ 200 ppm, TSA @ 100 ppm, TSA @ 200 ppm, TGA @ 100 ppm and TGA @ 200 ppm). The experiment was conducted in split plot design with 4 replications. Wheat sown at 20ºC showed superior performance in respect of dry-matter partitioning and yield parameters, i.e. grain, straw biological and yields as compared to sowing at 22ºC and 18ºC. Amongst the bio-regulators options, an application of SA @ 200 ppm resulted in better performance, being comparable with those of TSA @ 200 ppm and TGA @ 200 ppm. Crop sown at 20ºC along with SA @ 200 ppm was found to be a better option for maximum dry matter accumulation and productivity of wheat under heat stress.

The present investigation on evaluation of varietal performance of various potato varieties under Pune Conditions was initiated in Oct 2012. Potato tubers of Kufri Lauvkar, Kufri Badshah, Kufri Pushkar, Kufri Surya, Kufri Khyati, Kufri Ashoka, Kufri Jyoti, Kufri Pukharaj were planted on ridges and furrows. The results revealed that Kufri Surya recorded significantly higher total tuber yield (20.67 t/ha) followed by Kufri Pukharaj (18.45 t/ha). However percent plant emergence and foliage senescence were found non-significant. Whereas results in respect of yield depicted that the variety Kufri Lauvkar produced the lowest tuber yield of 16.23 t/ha. Tuber dry matter (19.69%) was recorded to be the highest in Kufri Surya which was significantly superior in comparison to the remaining varieties. The least incidence of late blight (9.69%) was recorded on Kufri Khyati which was at par with K. Surya (9.74%). The least incidence of early blight (10.29%) was recorded on K. Lauvkar which too was at par with K. Surya. Keeping this in view K. Surya may be recommended as promising variety for Pune region

Field experiments were conducted during Kharif-2017 and 2018 at ICAR-Krishi Vigyan Kendra (KVK), Mangaluru of coastal Karnataka to study the effect of integration of organic and inorganic sources of nitrogen on the yield of midland rice. The results indicated that the integration of organic and inorganic sources of nitrogen significantly influenced the growth and yield attributes of rice. The highest grain yield (5434 and 5372 kg ha-1) and straw yield (6817 and 6927 kg ha-1) were recorded in the treatment comprising VC substituted with 50 percent recommended dose of nitrogen which was on par with PM substituted at 50 percent in both the years. A similar trend was also noticed in both the years for the growth and yield parameters where the highest plant height (94.93 and 96.30 cm) highest productive tillers (16.85 and 18.12) and longer panicle length (17.54 and 18.65 cm) was recorded in the treatment where 50 percent nitrogen was substituted by vermicompost compared to control. The remaining treatments of organic substitution ratios with urea also had a beneficial effect on yield and yield parameters of rice compared to control.

A field experiment was conducted during kharif 2013 and 2014 to study the effect of row spacing and sowing time on seed yield, galactomannan and protein content and nutrient uptake of guar in semi arid climate of Southern Telangana. The crop sown at row spacing of 30 cm recorded significantly higher seed yield than that of 45 cm and 60 cm spacing. Production and rainfall use efficiency and harvest index besides growth and yield attributes, galactomannan and protein yields, N, P and K uptake were also significantly higher at 30 cm spacing. Sowing of guar during first or second fortnight of July resulted in significantly higher seed yield than first fortnight of August sowing. Production efficiency, plant height, number of clusters plant-1 and protein yield followed the similar trend of seed yield. Negative relationship was observed between galactomannan content and sowing time. Though powdery mildew infection was higher in early sown crop and close crop spacing, higher plant population and biomass production resulted in higher seed yield of guar when compared to late sown crop and wider spacing.

The objective of the experiment was to determine effects of Brassinosteroid (BRs) concentrations on growth, development and yield of Jasmine 85 rice cultivar under salinity conditions at panicle initiation stage. The experiment was laid out in a completely randomized design with three replications and consisted of two factors. The first factor comprised three salinity concentrations: 0‰ (control), 2‰ and 4‰ and the second factor had three concentrations of BRs: 0 ppm (control), 2 ppm and 4 ppm. The results showed that under non-saline conditions, the control rice plants sprayed with BRs at a concentration of 2 ppm had the highest values of root length (33.39 cm), leaf area (42.41 cm2), proportion of firm seeds (72.20%), weight of 1000 seeds (28.14 g) and yield (725.55 g/barrel). At the salinity level of 4‰, rice plants sprayed with BRs at a concentration of 2 ppm demonstrated the highest levels of APX and CAT enzymes. Briefly, rice plants grown under higher salinity levels had decreased growth and yield. Spraying BRs helped improve growth and yield parameters of rice under high salinity conditions.

A field experiment was conducted to study the effect of different planting techniques (conventional drill sowing at 16, 18 and 20 cm row spacing and bed planting with two and three rows in main plots) and weed control treatments (pinoxaden 50 g/ha, ready-mix (RM) of carfentrazone and metsulfuron 25 g/ha and pinoxaden 50 g/ha + RM of carfentrazone and metsulfuron 25 g/ha in subplots) on growth and productivity of wheat. The grain yield under row spacing 18 cm (53.30 q/ha), and 20 cm (52.02 q/ha), and three rows bed planting (51.96 q/ha) were recorded statistically at par with each other and significantly higher than 16 cm (49.37 q/ha) row spacing and two row bed planting (48.53 q/ha). Gross returns (Rs. 95637/ha) and net returns (Rs. 43929/ha) and B:C ratio (1.85) were record-ed higher under 18 cm row spacing compared to other planting techniques. Tank mixed application of pinoxaden 50 g/ha + RM of carfentrazone and metsulfuron 25 g/ha applied at 35 days after sowing (DAS) controlled both grassy and broad leaved weeds effectively with lower values of weed dry matter accumulation (7.67 g/ha) and produced growth parameters, yield attributes and yield (53.16 q/ha) at par with weed free treatment. In light of the results to maximise productivity, 18 cm row spacing may be practiced and tank mix application of pinoxaden (50 g/ha) + RM of carfentrazone and metsulfuron (25 g/ha) is recommended to reduce losses due to complex weed flora in wheat.
