Abstract There is no available information in determining soybean varieties that shows tolerant when intercropped with maize. The objective of this study was to determine soybean varieties suitable for intercropping, based on changes in plant growth and yield when intercropped. The field experiment was conducted from October 2019 to February 2020 based on RCBD with 2 factors. The first factor was soybean with 16 national varieties. The second was cropping systems i.e., monoculture and intercropping. Morphology and yield data were observed and subsequently analysed based on performance difference (D) of each parameter between intercropping and monoculture. Tolerance level to cropping systems with maize was grouped based on the yield-based and selection index calculations. The results showed that different cropping systems affected morphological and yield parameters on 16 tested soybean varieties. Seven varieties i.e., Derap 1, Devon 1, Devon 2, Demas 1, Dena 1, Dena 2, and Wilis were grouped as tolerant to intercropping with maize. Among these, Derap 1 was the most tolerant variety.

The Pacific Northwest dryland region is moving toward conservation tillage to control excessive erosion on steep slopes, but progress has been slow because of adverse effects on plant growth and yield. Fertility relations in cereal grains with conventional tillage are well known, with deficiencies occurring for nitrogen, sulfur, and phosphorus, in declining order of frequency. N and S deficiencies are more severe in conservation tillage, although the pattern of crop response to nutrient application is the same as in conventional tillage. Placing nutrients in a subs urface band near the seed is more effective than broadcasting on the surface. Higher fertility is required near developing root systems to offset greater competition from grassy weeds and more intense pressure from root-pruning soil pathogens. Conservation tillage alters soil fertility and plant growth in different ways on different landscapes. These differences must be considered to ensure tha t conservation tillage will be effective over the entire field.

The experiment was conducted to perceive the effect of fungicidal seed treatment on growth and yield parameters of green gram cv. GM-3 with nine different fungicides. The results revealed that dry seed treatment with either mix formulation of carbendazim+mancozeb or thiophanate methyl or carbendazim @ 2.5 g kg-1 seeds is very effective in field to get maximum seed germination, better plant growth, root growth, yield parameters and yield. Seed germination was maximum in dry seed treatment with carbendazim + mancozeb (83.85%) which was statistically at par with thiophanate methyl (83.58%), carbendazim (82.53%) and captan (80.77%). Plant height was maximum in dry seed treatment in mixed formulation carbendazim+mancozeb (41.53 cm) which was statistically at par with thiophanate methyl (39.91 cm), carbendazim (39.67 cm) and captan (37.00 cm). Average numbers of pods plant-1 were maximum in dry seed treatment with carbendazim+mancozeb (12.33) which was statistically at par with thiophanate methyl (12.17), carbendazim (11.90), captan (11.85), thiram (11.58) and difenconazole (11.09). Average numbers of seeds pod-1 was maximum in dry seed treatment with carbendazim+mancozeb (7.58) which was statistically at par with thiophanate methyl (7.48), carbendazim (7.31), captan (7.28) and thiram (7.12). The pooled data of two years indicated that grain yield was significantly higher in dry seed treatment with carbendazim + mancozeb (818.40 kg ha-1) as compared to the rest but was statistically at par with thiophanate methyl (790.73 kg ha-1) and carbendazim (771.35 kg ha-1) followed by all the other treatments.

The productivity of agricultural produce is fairly dependent on the availability of nutrients and efficient use. Magnesium (Mg2+) is an essential macronutrient of living cells and is the second most prevalent free divalent cation in plants. Mg2+ plays a role in several physiological processes that support plant growth and development. However, it has been largely forgotten in fertilization management strategies to increase crop production, which leads to severe reductions in plant growth and yield. In this review, we discuss how the Mg2+ shortage induces several responses in plants at different levels: morphological, physiological, biochemical and molecular. Additionally, the Mg2+ uptake and transport mechanisms in different cellular organelles and the role of Mg2+ transporters in regulating Mg2+ homeostasis are also discussed. Overall, in this review, we critically summarize the available information about the responses of Mg deficiency on plant growth and development, which would facilitate plant scientists to create Mg2+-deficiency-resilient crops through agronomic and genetic biofortification.

Moringa (Moringa oleifera L.) leaf extract is a natural plant growth stimulant that is well-known for its ability to improve plant growth and development. A field study was conducted to evaluate the influence of MLE (Moringa Leaf Extract) on the growth, yield and nutritional improvement in two vegetable crops [Tomato (Solanum lycopersicum) and Indian Spinach (Basella alba)]. The extract was applied at two weeks interval with different frequencies. The crops were fertilized with chemical fertilizers and MLE application was done as per treatment @ 25 ml/plant. For each of the crops, this bio-stimulant had a significant boosting effect on growth, yield and nutrient uptake whereas the maximum frequency in the application i.e. T4 (foliar application of MLE at 2 weeks after transplanting and application at every 2 weeks thereafter) showed the highest influence. Indian Spinach responded proportionally more to foliar-applied MLE in terms of plant growth and nutrient uptake compared to tomato. The effect of MLE on the yield parameters was more pronounced in tomato that showed a 25% (averaged across all the growth parameters) increase over control, but Indian Spinach showed ~20% increase in yield parameters compared to control. Therefore, applying MLE to the foliage may assist in increasing the yield by improving plant growth across the different vegetable species (e.g., Tomato and Indian Spinach).

Lilium is one of the most important cut flower and ranks second among bulbous flowers in international market. The scope of the study lies in the fact that despite having the congenial climate of Kashmir for bulb production, the cultivators are importing the bulbs from abroad, so there was need to rationalize the nutrition for optimum plant growth and bulb yield of lilies under Kashmir valley conditions. Consequently, an investigation was undertaken to evaluate the differential response of Asiatic lilies cultivars to different methods of application and nitrogen sources (urea and calcium nitrate) in terms of plant growth, bulb development and yield. Significant differences were observed in growth parameters and behaviour of two cultivars viz., Serreda and Navona. Calcium nitrate significantly improved plant height, leaf area (LA) and LA index (LAI) recorded at 50, 75, 90, and 105 days after planting (DAP). Bulb yield parameters (weight of mother bulb, weight of bulblets, number of bulbs plant-1, propagation coefficient) varied significantly between the two cultivars. Calcium nitrate significantly improved bulb weight, bulb circumference, the number of bulbs plant−1 and propagation coefficient. However, the effect of three and four split nitrogen application on plant height, LA and LAI was significant at 90-105 day interval. Ca(NO3)2 was more effective in ensuring the prompt availability of nitrogen to plants as compared to urea (NH2CONH2); also it was advantageous for improving the bulb growth because of presence of critically important micronutrient i.e. calcium. Split application of nitrogen was advantageous not only in improving the growth and yield attributes but also in preventing the significant losses of nitrogen caused by various processes such as leaching.

Black plastic mulch is used predominantly for winter strawberry (Fragaria ×ananassa Duch.) production in Florida because of its warming effects. However, black plastic mulch can increase heat stress during establishment, especially when growers advance planting dates (e.g., late September) to improve earliness. Consequently, we designed a new plastic mulch film that has a metalized center stripe with black shoulders. We hypothesized that metalized-striped mulch can minimize heat stress during establishment, while maintaining the warming effects of black mulch during winter. We conducted field trials over two seasons to evaluate black mulch, fully metalized mulch, and metalized-striped mulch using two cultivars differing in heat stress tolerance and fruit production patterns: ‘Florida Radiance’ and ‘Florida Beauty’. The effect of plastic mulch type on plant growth and yield was generally consistent across both seasons. Compared with black mulch, metalized-striped mulch reduced afternoon root-zone temperature (RZT) by up to 3.1 °C and reduced the duration of heat stress conditions (RZT > 30 °C) by 119 hours across October and November, but exhibited equivalent soil warming during winter. Yield increases by metalized-striped mulch compared with black mulch ranged from 19% to 34% in the early season (November–January), 6% to 20% in the late season (February–March), and 12% to 26% over the entire season. Statistical significance was detected for the 2016–17 early-season yield and when yield data were expressed on a weekly basis. Compared with black mulch, metalized-striped mulch improved fruit number significantly without affecting fruit weight or canopy area, suggesting that heat stress on black mulch negatively affects flower and fruit development more than plant growth. Weekly fruit yield data indicate that metalized-striped mulch can produce greater yields than fully metalized mulch. Metalized-striped mulch is an easily implementable strategy for reducing establishment heat stress and improving fruit earliness in subtropical winter strawberry production regions.
